Comparing the Unit X Stretch to the Nuttsling

Comparing the Unit X Stretch to the Nuttsling

Over 1 ½ years ago I reviewed Oxballs’ Nuttsling and it instantly became one of my favorite toys. So when Uberkinky offer me a review sample what Oxballs positioned as a more modern update to their “old” sling line I was instantly intrigued. So instead of a traditionally review I am comparing the new comer to the old champion to see who will be leaving this Oxballs family fight as a winner.

Construction

The Unit X Stretcher follows the same basic constructionas the Nuttsling with three holes: One hole through which you put your balls and dick which is oblique for a comfortable fit when it is pressed onto your body and a hole each for your dick and your balls. While the Nuttsling had a more industrial look with bulges for reinforcements the Unit X Stretch uses thicker material and a rough sand clock shape to create the same compression resistance. Through this and an additionally internal bulge in the tube going down to your balls the sack’s neck is compressed a bit for a nice bulky balls look. The major difference to the Nuttsling is that the tube opens up a bit behind the bulge leading for a more comfortable wear. Generally speaking all holes and tubes are 1 to 2mm wider than on the Nuttsling so generally speaking this toy is a bit more comfortable to wear – despite the bigger stretch. The tube going down to your balls is now 51mm long vs. 35mm on the Nuttsling. This more of room and comfort apparently lead to the omission of the recesses for your seminal ducts.

Material-wise a little bit has changed. Oxballs claims to have used a new TPR blend which is supposed to be more stretchy and rubber-like. For the stretch I can’t really tell. It is a bit easier to put on but I wouldn’t attribute that to the new material but to the larger holes. For the feel, yes it feels a bit different, not like rubber but a little bit smoother. More importantly: I felt that the shine stays on way longer despite extensive usage so it at least looks more like rubber.

Playing with it

In the review of the Nuttsling I said that it is made for really long-term usage. This applies even more to the Unit X Stretch. I have worn it on long parties, nearly all Folsom Europe, slept with it on for a night and never experienced any problems. This is due to the stretcher being a bit larger in any dimension and the tube going down opening up. The times I pinched skin when putting it on or walking around dropped to nearly zero. It is also a bit more comfortable to wear because the sand clock shape allows for little bit of collapsing on the narrowest point so the stretcher adjust a bit onto who much stretch your balls can take. This of cause doesn’t compromise the effect of a ball stretcher. The balls still bounce happily when jerking off or fucking and are hold properly far away from your body when they want to come closer for shooting your load making the orgasms more intense. In fact: Because my balls are a bit on the larger side I liked the extra 15mm stretch. The more of comfort doesn’t excuse you from a proper shave. Caught pubic hair between your skin and the stretcher can create quite sever pain when moving!

For putting it on nothing has really changed to the old model so I repeat my old instructions:

  1. putting both forefinger and middle finger inside the stretcher tube,
  2. squeeze and pull it apart,
  3. push the back against the point where your perineum meets your scrotum,
  4. pull the tube over your balls,
  5. than your dick through the hole and
  6. finally adjust the tube which will probably still be a bit deformed after the squeezing.

Despite the new material nothing has changed when it comes to lube. Oxballs still claims the new TPR blend is fine with any form of lube. I have tried it with water-based one, silicone lube and olive oil and Vaseline and it didn’t alter the surface. So even during a sloppy, messy fist scene with lots of Crisco it will stay nice and shiny. Another property of really all Oxballs TPR blends is that they don’t take over smells. So you don’t take the smoke smell of a crowded bar or other fumes from a dirty party back home. As expected the new blend also does not conduct electricity so the Oxballs Unit X Stretch can be used for isolating between two poles in electro CBT. The longer neck even allows for new interesting kinds of play: Until I have bought the Oxballs Zap last weekend in Berlin I used to stick two Mystim Silicone Pad Electrodes into the tube in order to fry the ball’s neck. I have to admit it is a bit of a challenge to place them there but the fun is worth the effort.

So at the end the question remains: Who is the winner? For me it is the Unit X Stretch. It does all the things the Nuttsling does just as good but a little bit more comfortable and with a little bit more stretch. To be honest I personally prefer the industrial look of the Nuttsling over the sprtoy streamlined one of the Unit X Stretch but when it comes to play

Conslusion: The new most comfortable ball stretcher I own with even greater long-term potential!

Detail of the Conductive Area and Strap

Detail of the Conductive Area and Strap

This review is about a basic e-stim toy nearly every major manufacturer carries. The one I have gotten were give aways with every electro box Mr S sold. Sadly they have stopped doing it and are not selling this particular toy anymore. So when reading this review please keep in mind that the actual measurements of different versions of this toy may vary! The way it works and the construction are all the same.

Construction

The main part of this toy is a rectangular plastic body. The bottom is made out of stainless steel for better conduction. On the one side of the top is a knob onto which the low profile lead is attached. The female side of this plug is made for 4mm bananan plug. The other side is a clasp through which the strap runs. It is made out of an elastic fiber and is approx. 17cm long and 2cm wide. The inside is made out of a conductive fabric.

Detail of the Clasp and Connection Knob

Playing with it

The operation of this toy is quite easy: Simply put it onto the desired body area, make sure that the heart doesn’t lie between the strap and the other pole and tighten the strap so that it is fastened securely. They basically fulfill the same purpose as the conductive silicone loops I reviewed some weeks ago. Yet they have some important differences. The most notable is the handling difference: The edges of the toy is not conductive so you can theoretically place both straps next to each other without short circuiting your box. When turning up the power please be a bit more careful than with these loops. Despite the larger contact area and the fact that the conducting area is pressed onto the body the higher conductivity (at least when I compare my straps to my loops) leads to a stronger effect which is a bit more stingy. You can take away a bit of the sting by using conductive lube or soaking the bands in salt water before play. Through this property they are useful when your sub has maxed your box with the conductive loops. From experience I would say that these straps give you another 30% more sensitivity but as always with e-stim this can vary depending on the sub and his physical condition. I also tend to use them when the sub is not restrained tightly and moves a lot and/ or has a small dick which might cause conducting silicone loops to fall off. Due to these loops being kind of stiff the elasticity of the cock straps helps when you want to attach electro to rough body areas.

Playroom Essentials: E-Stim Cables

Von | | , ,

This article shall give you an overview over the most common cables used in e-stim and what you might need them for. The first part of the article deals with the basic stuff that you need to connect your power box to electrodes from various different manufacturers. The second part shows some solutions for more elaborate forms of play.

While you can get most of the things from this article from the manufacturers of e-stim power boxes and toys or stores like Regulation or Mr S but you can also look at stores selling electronic components. Most of the time they are a little bit cheaper.

If you want to learn more about e-stim in general I have published a previous article on that topic. If you just want to know which e-stim box uses which connection standard read this article.

Basic Equipment

Left: 2.5mm jack onto 2mm pin lead Right: 3,5mm jack onto 4mm banana plug lead

Left: 2.5mm jack onto 2mm pin lead
Right: 3,5mm jack onto 4mm banana plug lead

Leads

They are the most essential cables you will need for electro play because they are used to connect your power box with the electrodes. They have a jack at the one end and a set of plugs at the other end. Usually there is a pair of plugs at the end, but there are also cables for more elaborate set-ups out there with four plugs. Depending on which system you are using they are combinations of 3.5mm jack and 4mm banana plug or 2.5mm jack and 2mm pin plug.

You can find so called “adapter” cables out there which mix 3.5mm jack with 2mm pin for example. They might sound handy but I would strongly dehort from using them! When you have different systems which mix all the different plugs and jacks I would identify the “major” system and use adapters (see below) instead of different leads. It will safe you a lot of money and space because adapters are lighter and more inexpensive than buying new adapter leads.

From left to right: 2mm pin onto 4mm banan plug adapter, 3.5mm jack onto 2.5mm jack adapter, 4mm banana plug onto 2mm pin adapter

Adapters

Adapters are nifty little units which you can put onto jacks or plugs in order to change their form factor, for example turn a 4mm banana plug into a 2mm pin plug. They are used to incorporate toys from a different connection standard into your play set up or in order to save money and space on special leads when you have mixed standards in you power box outputs.

Advanced Play

Tri-Phase Cables

A special form of leads are so call tri-phase cables. They either come as special cables or as an adapter to connect two leads. High-end e-stim boxes like the E-Stim 2b or the ErosTek 312b have special programs which enables you to create three spot of sensations for which you need these kind of cables.

Detail of Measurement Line Plug-Jack-Unit

Measurement Lines

This kind of cables is a pervertable from laboratories. They are basically two sets 4mm banana-jacket-plug-combinations connected by a cable that comes lengths of 25cm, 50cm and 100cm. You can use them to daisy chain multiple electrodes or use one electrode with different power boxes. The effects using measurement lines are hard to explain and the play is for the more experienced e-stim player so I recommend you play around with yourself a little bit before you put elaborate constructions onto your sub.

Detail of a Audio Extension Cable

Extension Cables

The play space or even electrode layout can require you to place the electro box farther away than your leads are long. In this case you can use extension cords to deal with the problem. They come in two varieties: The first are jack cables used in audio installations and come in a variety of length. Some systems like Mystim don’t use 3.5mm or 2.5mm jackets are output jackets or sometimes only one pole is quite far away. In this case you need extension leads. They are cables with a matching jacket and a plug of the connection system you use.

Pole connector clamps

Sometimes you want to incorporate metal toys like ball stretcher, cockrings or metal plugs into your electro play that were not made for e-stim. In order to connect them to your box you need pole connector clamps. They come in either isolated or not isolated varieties. Being another pervertable from laboratories they only come with 3.5mm jackets.

What they are not made for are to be put on different nipples! This kind of play is dangerous and potentially lethal!

Silver Coated Cooper Wire

A challenge to incorporate the metal toys mentioned about is finding a space to place the pole connector clamps. To overcome this challenge wrap silver coated cooper wire securely around a metal part of the toy you want to use as an electrode and attach the clamp to the wire. The wire can also be used as an electrode by wrapping it around different body parts or let it travel over the sub’s body. But please keep in mind: With little contact area and little resistance even little intensity levels can have agonizing effects. So you can employ this wire as a substitute to conductive silicone loops if a sub maxes your box with them.

Unboxing: Mystim Tension Lover

Von | | ,
2 Kommentare

Unboxings are one of the most common article forms on tech sites. So it is kind of ironic (and keeping the packaging of other toys in mind natural) that I somehow only do unboxings for electronic toys in this case the Tension Lover from Mystim.

Mystim sent me this E-Stim box earlier this week for testing purposes following the desiderate I published earlier. So I am already excited about using this box and see if it can live up to the things customer reviews promise. But before after extensive testing I am going to write a review in a couple of weeks let’s see what’s in the box.

The toys comes in a nice and sturdy black plastic case. It measures 26x21x5,5cm and can be shut be two magenta colored plastic sliders which securely lock the lid.

_DSC0035-2

The inside of the box is lined with hard grey foam. On the right there is a section for the Tension Lover and a 9v block battery. This takes up about a third of the space so there is enough space to store additional electrodes alongside the power box.

_DSC0036-2

_DSC0037-2_DSC0038-2The power box itself is made out of black plastic and measures approx. 13x7x2,7cm. It lies good in the hand and with the big display and the sliding cover over the control buttons it feels a bit like an old cell phone (yes, I am THAT old).

On the top are two dials to control the intensity and a socket for each of the two channels. Also in the picture you can see the belt clip on the back.

_DSC0040-2

The box comes with two leads, one for each channel. The end in 2mm pin plugs so you need adapters if you want to use them with p.e. toys from E-Stim.

_DSC0041-2The next item out of the box is the quite informative manual that not only explains how the box works but also gives a good beginner’s intro into E-Stim. A nice bonus is the chapter on how you can use the box for pain therapy.

_DSC0043-2The Tension Lover can be ordered in two versions: The one which I have gotten with sticky pad electrodes for 139.90€ or one with the silicone pad electrodes that I have already reviewed here for 149.90€. It is a nice touch that they already provide simple yet versatile electrodes so you are ready to play right out of the box.

_DSC0044-2In order to do so Mystim also put a 9v block battery into the case so you can start playing right away.

_DSC0046-2As already written: With basic electrodes provided, a good, informative manual and an easy to use power box I think the Mystim Tension Lover is a good beginner’s electrode box from the first look. Now I can’t wait to try it out. If you live around Hamburg/ Germany and would like to become a testee – either top or bottom – send me an e-mail.

On the show I mentioned HML Velcro restraints. So if you are interested in learning more about these restraints, click here for a review of the normal restraints, an update on the heavy duty and ankle version and a short intro into the hand stirruos. The prices of the restraints range from 49.90€ to 149.90€. They also make unique gear like a bondage harness. If you are in the market for light weight yet heavy duty restraints I would recommend ordering them because by doing so you are not only getting a great piece of gear but support a local, small and creative kinky business.

E-Stim Electro Whisker

Einen Kommentar hinterlassen

electrowhiskLike every year for Folsom Europe this website went a bit quiet and will be back next week with the final stretch of the e-stim special. However during Folsom Europe I had the chance to try out a wonderful devious and delicate toy I want to introduce as a desiderate: The E-Stim Electro Whisker from Regulation.

It is a whisker made out of thin conduction stainless steel rods that packed into an isolated shaft. On top of the shaft is a 4mm banana jacket for connection to your power box. This toy is quite devilish: Because the rods are quite flexible you can vary the contact area very rapidly. So the sensation can momentarily change from a mild tingle to a hellish sting. The toy costs £40 directly at E-stim or £53.99 at Regulation. I had so much fun with it as a top and a sub, I can’t wait to add it to my collection!

Mr S Electrified World’s Most Comfortable Butt Plug

The Mr S Electrified World's Most Comfortable Butt Plug Size Large

The Mr S Electrified World’s Most Comfortable Butt Plug Size Large

This is one of the few instances where I review a toy that I do not own and have been lent for extensive testing. I have used the large version of this toy multiple times as a top and had it used on me. Additionally I have talked to people who have owned it for many years so I believe I have a quite educated opinion about it despite now owning it yet.

Construction

As the name of the toy says this is an e-stim version of Mr S’ extremely popular World’s Most Comfortable Butt Plug. The large version that I could test myself had an 89mm long polished stainless steel head with a diameter of 44mm. The first quarter of the head is a dull cone which turns into a barrel of which the last fifth is again shaped like a dull-ended cone. The neck of the plug is an approx. 5cm long silicone covered flexible metal rope. The base is again made out of polished stainless steel and has a diameter of approx. 50mm. Onto the bottom of the base an approx. 1m long cord with a 3.5mm jacket is already soldered. Due to being made out of stainless steel the toy weights 396g including the cord.

There are two smaller versions out there: The Small with a head diameter of 3.2cm and weight of 226g and the medium with 3.8cm diameter and a weight of 312g.

Detail of the Flexible Neck

Playing with the toy

Once inserted and plugged into your electro box this plug due to the surface size and large mass delivers a smooth yet intense sensation. Due to the thin and flexible neck I found this toy quite comfortable to wear for long-term sessions. Because the sphincter can nearly fully close despite the heavy weight I never feared that the massive head would fall out of my ass or that the base would be sucked into it. But you still feel the massive piece of heavy steel in your bowel which is quite a turn on. Due to the connection between base and head being flexible it can’t sadly be influenced where head rests so a controlled prostate stimulation is very difficult to achieve.

I have to be honest: When I first held this toy in my hands I was not sure about the soldered cord. When you sit on the plug it bends quite a lot so after long usage I would expect a lead fracture. This would be especially annoying because since the lead is soldered onto the base you can’t just exchange the cable but have to solder it again. However I have talked to people who have been owning this toy for many years and never experienced a lead fracture so I guess even with this design Mr S stays true to their high quality standards. Where the soldered lead becomes a problem is when you want to dive into more elaborate electro play, strictly speaking when you want to work with tri-phase programs. The ErosTek ET312b and the E-Stim 2b can create a “virtual” third stimulation point through tri-phase cables or adapter. In order to do so you take a pole of two channels and connect it to a third electrode. Since you plug the Electrified World’s Most Comfortable Butt Plug directly into the box you can’t pick off a pole. The same problems comes up when you want to integrate it into a pole daisy chain using laboratory leads or use it as a heavy mass monopole. You can substitute this by using a one-jacket-two-plug-cable but will still end up with a bi-pole on one end.

Detail of the Soldered On Lead

Detail of the Soldered On Lead

When choosing the right size of this toy I advise you to be a bit conservative. Being made out of stainless steel the material won’t give in so if you just can take the maximum diameter with a vinyl toy choose a smaller size. Due to the flexible connection between head and base you can’t or should not push and pull the head in holding onto the base. So the head should go in with some ease.

For this toy the same rule regarding lube applies than to the conductive silicone toys I have reviewed earlier: Do not use silicone based lube because it will destroy the coating of the neck and will work as an isolator.

Don’t get me wrong: It is a good electro plug, excellent at delivering an e-stim sensation. But when you are a perfectionist like I am who wants an indestructible toy that leaves you with all the possibilities you can theoretically have, I would recommend to look elsewhere.

Conslusion: Good bipolar E-Stim Plug with slight Handling Shortcomings.

The Mystim Tension Lover with the Case and its Contenct

The Mystim Tension Lover with the Case and its Contenct

A couple of weeks ago I answered to your request for a novice electro box with writing a bit about the E-Stim Intro Packs. Yet I got some requests if there isn’t a box out there with two channels that isn’t too expensive and indeed there is: The Mystim Tension Lover.

It is a fairly basic yet sophisticated box. It is digital with a large display so you can adjust the programs quite accurately. There are only 7 programs and no audio interface but for a first dip into e-stim pleasures (or pain) it is quite enough. It also has a timer function if you want to leave your sub alone. A nifty feature is the locking of the keys of you want to walk around during the stimulation.

Since I was always looking for a another compact digital electro I am very much looking forward to owning this box some day and would love to review it! The box comes in a nice case with two leads and four pad electrodes and costs £119.99 and can be ordered from Uberkinky.

The Mystim Plunging Pete ontop of the Packaging with the provided Set of Leads

Construction

The foundation of this toy is a conductive silicone loop made to be put around your glans. Onto this loop an isolated pin with another tube of conductive silicone is attached which runs perpendicular through the collar that holds the loops’ ends together. On this vertical tube are three 24k gold plated spheres located with the middle one having 35mm long and 4mm thick rod attached.

The toy comes in a nice tin box along with a set of leads for attaching to a Mystim power box and two samples of their own conductive lube.

Playing with the toy

Detail of the Leads attached for Monopole Play

Detail of the Leads attached for Monopole Play

This toy is one of the few toys that enables you to make bi-polar glans play. Before I have gotten it I have often tried to attach two silicone loops to the glans or use a pad at the frenulum and a loop around the glans. But it is complicated to get both electrodes securely attached without the two touching. Through the nifty collar design of this toy this problem is solved. In order to put it onto the glans adjust the two silicone tubes until the toy sits securely on the glans and both tubes have skin contact. While the tubes are long enough to fit even extreme large dicks I found the attachment process a bit complicated: The isolated carrier for the vertical tube can’t be moved. So in order to keep it in the middle you have to adjust both ends of the horizontal loop which is a bit tricky especially when you have lube on your hands. Because of that I would always recommend attaching the leads once the toy has been adjusted.

In order to attach the box onto this electrode simply put a 2mm pin cable or adaptor into one of the open tube holes. If you want to use the toy as a monopole, choose one of the three endings, if you want to use it as a bi-pole use the vertical and one of the horizontal ending. Do not use both horizontal endings because it will short-circuit your box by doing so will damage it!

Detail of how the Toy can be Transformed by moving the Gold Plated Spheres

Detail of the Collar holding and seperating the two Silicone Tubes

Mystim produces three versions of this toy: The Pure Pete with just the two silicone loops, the Pearly Pete with three gold plated spheres and the Plunging Pet which I will review here. I decided to buy the Plunging Pete because it is all the three versions in one. If you pull the horizontal silicone tube out of the collar you can remove the there attachments in order to create the Pure Pete. Turn the sphere with the rod around and you have the Pearly Pete.

I have to admit it takes a bit of getting to know this toy in order to create the wide array of sensations that it can create with the right power box. The most important part of this toy are the gold plated spheres resp. the rod. Through the material they are highly conductive and due to the round shape the contact area is quite small so even with little power is enough to create a noticeable effect. It is one of the few toys I know that can create a non-painful tickling sensation.

Detail of the Collar holding and seperating the two Silicone Tubes

Detail of the Collar holding and seperating the two Silicone Tubes

The art of mastering this toy is knowing there to put the spheres. When you want to milk someone I would recommend only placing one sphere on the frenulum. In order to make this sensation a little bit more torture like you can put the rod into the urethral. Another possibility is to put two spheres on the horizontal loop and one on the vertical for a really agonizing effect. When you remove all spheres you can adjust it so tightly that it can be comfortably worn for an entire day without falling off making it ideal for remote control commando e-stim play in public. For that purpose and if you use the toy only on one sub I would recommend shortening the silicone tubes because in order to fit even XXL dicks they are quite long.

As always when I talk about conductive silicone toys here the reminder NOT to use silicone lube when playing with this toy. Depending on the brand it is more or less isolating and it will dissolve your toy! Cleaning this toy is not different than any other toy: Use a mild detergent in warm water, let it dry and disinfect it. Since the rod is supposed to be inserted into the urethral be sure to disinfect it thoroughly after and right before play in order to avoid nasty infections.

Conclusion: Very well designed and versatile yet a bit tricky to use glans toy.
