Vendor: SquarePeg

Almost 30 years ago, SquarePeg was the first ever company to manufacture anal toys for the kink market out of platinum silicone. Scott, the founder of SquarePeg is a trained woodworker and sculptor. His profession in combination with being an avid anal aficionado and through this interested in rectal anatomy led to a very special approach in toy design: Each toy is carefully designed with a special purpose and stimulation inside the anus, rectum, sigmoid and colon in mind. So while his toys are not the biggest or the most complex, they are the easiest to handle and control ones that deliver targeted stimulations which can quickly drive you to ecstasy (or anal orgasms).

Before I dive into the review of these three depth toys, a quick shortcut for all who want to start out with depth play: These are not beginner’s toys! If you want to explore depth, buy a SquarePeg Thick Worm. In my opinion the best toy to slowly stretch and desensitize your second sphincter and sigmoid. If you already have a bit of depth experience or are curious about the what toys will await you in your journey deep down, welcome to this review!

Construction

Back in 1997, Scott decided to make toys out of platinum silicone not only it was the easiest material to handle for small edition but also for its material properties. Back then, rubber and vinyl toys which then almost all emitted dangerous plasticizers (those old enough can still remember the distinct sex store smell) were the standard. Using a 100% body safe material like platinum silicone (and still one of the few companies only using US made raw materials) was revolutionary in the old millenium.

As someone how likes to play hard, the super-smooth surface which not only made taking the toy easier but also kept bacteria from lingering was an advantage. To clean silicone toys, simply throw it into warm soap water, sanitize and you are ready to use it on someone else, making it the perfect material for group settings.

The only drawback is, that silicone toys must not be used with silicone lube. The silicone lube will solvate the silicone, leading to a sticky surface and over time will disintegrate the toy. If you stick to water- or oil-based lubes you will be fine. Since platinum silicone is the material also used for medical purposes, a well kept toy will bring fun to your heirs….

Silicone can come in various firmness degrees but SquarePeg only offers two: Supersoft and Firm. For various reasons, they do not publish firmness degress but my best guess is that the Supersoft is somewhere between Shore 00-20 and 00-30, the firm more at 00-50. Beware: The thicker a toy is, the firmer and less flexible it will feel.

While silicone can easily take on color and thus is now popular with fantasy toy makers, SquarePeg (used) to have a simply color scheme: bronze and grey called graphite for Supersoft, black for firm. Now you can also get Supersoft in black. They puppy tails can be ordered in 13 colors and a small number of toys come in purple, but bronze, grey and black are the main and thus iconic colors for SP.

Playing the Depth Probe v4.0

The toy name is very telling. It is a toy to probe the depth of your colon. Back in June of 2018 I reviewed the first (?) depth probe. Frankly, I do not know where the v4.0 in the name comes from since I have not been aware of design changes. Maybe SP did two design experiments which never reached the market until the new one was released? But as far as I know, only these two version are available so don’t be confused by the name.

The new depth probe starts out with a pointy, slightly inward curved tip. Below the tip is a 1mm drop. Then over the length of one inch it slightly increases in size until dropping again. This continues with continuously slightly decreasing diameter until you the bar-shaped bottom.

The only design element the new depth probe shares with his predecessor is the handle at the bottom. It is large enough to be comfortably accommodate four fingers and still allow for a good grip. That makes the toy easy to control.

On the old toy the tip was a dull, 5cm long thickening which “forced” its way through the colon. With the new design the pointy tip can slip into a tight opening. Since the tip is bend and tapers conically, you can slowly widen and relax the tight spots by turning the toy while moving it slightly back and forward. This is a huge improvement and makes going deep easier and way more enjoyable.

The previous model has a smooth shaft with depth markers in inch embossed into the shaft. The new segments have several impact into the experience. They at a slight bit of stability as there are not “weak-“ or bendspots every inch which makes the toy a bit less slippery. The texture also adds stimulation by slightly massaging the sphincters. On the other hand, the added texture and stimulation also makes taking the toy a bit more difficult while at the same time makes it a bit more difficult to push out. So making pauses in the process is a bit easier. Overall, my testees enjoyed the pointy tips way more as they were irritated by the texture. So I would call the new design a win.

The Depth Probe v4.0 comes in three sizes: Slim short at 378mm length, a diameter tapering from 27mm at the tip to 25mm above the base and costing $79, medium with 521mm usable length, a taper from 37mm to 32mm at $129 and finally the slim ling with an enormous length of 1021mm and tapering from 34mm to 28mm for $189.

For my toy collection I chose the medium length for several reasons: The slim short is so short that I have slim dildos which are longer. For petite guys this might be a sensible size but every toy shorter than 400mm usable length is not a depth toy in my books. The slim long is so long it is hard to control to the degree of almost not being usable. Especially with lubey hands it flops around. The handling improved once about half the toy is inside the bottom – which is one medium depth probe length being quickly pushed into the bottom which is only possible with a very experience depth player. I once had the “pleasure” of playing with the slim long and being so long and slim, it gave me a bit of colonoscopy vibes once we passed the halfway point. When playing with such a long toy on a small bottom, you need to be careful not to cross from the large to the small intestine. This can lead to potentially lethal infections!

Playing with the Slink Tickler and Slim Longneck

Apparently, this is the review of curious product name choices. While I understand why one toy is called a a Longneck and for the other I can deduce why it is called a Slink, they are so similarly designed that I will review them together.

What I don’t understand is the name choice for the Slink Tickler! Back in 2020 I bought and reviewed a Slink textured with bumps all over the shaft from Regulation, called the Slink Tickler. This particular version of the Slink is not sold anymore so I guess the name is now free for a toy designed to tickle you deep down. But if you talk about the Slink Tickler low, make sure you and your conversation partner are meaning the same toy.

Both toys start out with a drawn out pointy head that has a small kink where the steepness increases thus mimicking the shape of a hand ready to fist. On the Slim Longneck the 95mm long head is almost round measuring 42x45mm at its widest and the kink is on the upper this. At the top’s bottom of the head there is groove which I first thought was a dent the toy got during storage in my playroom. But the same dent was on the product pictures. Neither my testees now I could figure out what the groove was for as it was not noticeable. If you have felt it or figured out what it is for, let me know! On the Slink Tickler the head is 5mm longer and flatter at 32x42mm with the kink in the middle.

Below the head the shaft is round and smooth. It gently increases in size like on all Slinks. The Slink Tickler increased form 28mm to a max diameter of 57mm before quickly tapering towards 38mm and then flowing into the base. On the Slim Longneck the initial diameter below the head is 33mm. It gently tapers to about 40mm before just below the neck there is a plug-like increase in diameter to 55mm before quickly tapering to the necks 42mm.

The base of both toys is oval and tapering towards the neck. While it is not as easy to grip as on the Depth Probe, you still have a good level of control. A nifty design feature of the base is the point. It tells you where the tip is pointing towards, making navigating the toy a bit easier when pushing the toy into a bottom.

The Slim Longneck is only available in firm black and costs $119. The Slink Tickler costs $169 and is also available in Supersoft Bronze and Graphite. After having played with the Supersoft versions, I went for the firm because they are so floppy and hard to control with lubey hands. Since the shaft of the Tickler is so thin, the material of both the head and the upper half of the shaft is still what I could consider soft and very bendy so going deep even around tight bends is easily possible.

If you want to go – to quote the Doors – deep and wide, SP also offers Longlong Neck with is REALLY long and thick!
