The Tentacle Depth Trainer III

Sale price£49

The suckers land exactly where you want them, the girth builds slow and patient, and the length gives you somewhere genuinely new to go (this is the Final Boss of depth trainers, we don't say that lightly). If you're eyeing the large and quietly panicking, good news, the tapered point eases you in inch by inch and it's body-safe platinum silicone, so the only thing you're committing to is going deeper than you planned. Top-heavy by design, narrowing gracefully towards the base, because gravity should be doing some of the work here.

Suckers everywhere

The precisely placed suckers give you texture inside and out, so grinding against it is nearly as much of an event as taking it. Full, squishy, relentless in the nicest possible way.

Slow and steady

It starts at a fine point and widens as it goes, so you set the pace inch by inch rather than the toy setting it for you. Fair warning: the large is a proper handful, so expect the biggest sizes to be a two-hands situation.

Heavy and flawless

Poured in body-safe platinum silicone with a smooth, flawless finish and real weight to it. Warm water and toy cleaner, tuck it away, no lingering evidence.

Reviews

What our customers say

The recurring praise is size, weight and the suckers, with people crossing off depth milestones they didn't think possible and singling out the super soft firmness as the standout. The gradual taper gets consistent credit for making a genuinely large toy easy to insert. The one honest gripe: at the biggest sizes it can be slippery and hard to hold one-handed, and a couple wished for a wider base for better suction hold.

Best tentacle ever

Absolutely amazing tentacle!! The colouring is so beautiful and the feel is amazing, so impressed with how perfect it is!

Great depth toy, fun very light texture

Great depth toy, fun very light texture. Almost 5 stars.

However, The texturing on the base is very... complicated? It's full of hundreds of tiny very pronounced indents that I'm worried will be a nightmare to clean thoroughly if they get dirty. I've been considering using the toy with a condom over the base just to keep it clean.

But otherwise, fun mild texture and great challenge.

Almost autonomous

Even with the dice for scale, the pictures don't do it justice. It won't fit in my sink!
Furthering my surprise was how it not only easily penetrated, but then slid farther and farther inside.
With how much kinking and flopping I was used to when inserting dildos (different Brand), this felt like it had gained consciousness to home in and insert itself! (quite the unexpected company on a lonely night)
Never would I have guessed just how deep I could go on the first night!
After praising so much I should mention that I am talking about the super soft mix.

The werwolf dildo was a free gift and I must compliment the team for picking complimentary colors in light AND in glow in the dark.

The german customs, however, were a nightmare. They alone kept this express shipment for 11 Days! And charged duty again! One nice email later, Uncover Creations refunded the amout duty took.

With this service and quality I feel obligated to buy again!

First depth trainer, suction cup heaven

This is the first depth trainer I’ve ever bought. Uncover Creations has never failed me, so I knew it would be worth buying one of their models. I picked this one for the suctions cups because I love the texture of the tongue on my oni grinder and this looked similar. It was even better than I expected 😍 This thing had me seeing stars just grinding against it! I did not think I would initially be able to insert all of it vaginally but I managed to insert all but the last half an inch or so on the first try Thanks to its flexibility. I tried it anally once and although I am very new to that sort of ”play” I was still able to insert it much further than I would have expected. Its gradual taper makes it very easy to ease it into whatever “door” you want to use. (It should go without saying, but definitely make sure to thoroughly clean your toys if you’re going to use both “doors”—no one wants an infection!) I also love the cute little anemones on the base. Very pretty details on this guy! Last but not least, I love the lavender and gold color combination that I got from the surprise me premium pour. I had a lot of ideas, but ended up going for the surprise me option. This tentacle matches my dragon knot four and the other tentacle in this order has a similar ocean theme. I’m super happy with this order. Big thanks to customer service for always being helpful, friendly and kind whenever I had questions. I’m a loyal, repeat customer for good reason! Pictured with my tentacle knot with cum tube, dragon knot 4, free mystery dildo and two small love eggs for scale.

Intro to Depth and Cum Tubes!

I normally go for girth but decided to try something different and see if I liked deeper stimulation. I wanted to find a toy with a cum tube to make sure I didn’t cause myself any injuries also. After a search I came across this toy and I knew I had to have it. New toy, new company, and new depths. Decided to get the custom color too since I’ve never done that with any toy. It came out beautiful! I only wish it could’ve had a suction cup and it would be perfect. I’ll buy from sinnovator again after I get used to this bad boy.

My depths have been thuroughly plundered.

When I placed my order, I promised I’d leave a review if UC came through with another tentacled surprise in the mystery option — and they absolutely did. So here's the first review of items I purchased.

The result? Better than I imagined. I chose the medium in the squishy soft firmness, and it’s perfect — supple enough to stay comfortable with the right amount of lube, but still firm enough to hit all the right spots. It moves with me, not against me, and the weight gives it this oddly cozy presence — I may have accidentally found the world’s most unconventional weighted blanket. Though honestly… having two might solve the dilemma of do I use it as a toy or as a blanket nicely.

The girth is ideal for stretching limits gradually — no sharp transitions, just smooth, deliberate texture that makes it feel alive without ever crossing into discomfort.

My one suggestion is when ordering a Vac-U-Lock base it would be really cool if you could colour match to the toy.

TL;DR: When my lottery numbers finally come up, I’ll be ordering an entire school of these and living out my best deep-sea fantasy.

Thank you, UC — from one very satisfied customer.

The feels

Was anticipating that it should feel really good and it was. Turn it 180 and you get more good feelings.

This is something else

I was looking for a depth toy that was thick, tapered, had a neck at the bottom and a relatively smooth texture, this toy caught my eye and i didnt miss a beat

Naturally it was worth the wait, there were some problems with shipping internationally that was out of their reach, but with some constant attention from Jade, they managed to get it sent to my country and even offered to cover the customs clearance tax

The tip is gentle, the ridges feel smooth going in and it didnt poke or anything once inside, with a generous ammount of lube, one can easily take it to the base that conviently came with a vac u loc hole, which could fit either a suction cup adaptor, or even a bullet vibe for even more intense feels

Overall its a fantastic toy, i can only recommend using some pair of biker gloves if going solo because its quite heavy and slippery when adequately lubed (monster can for scale)

Great product! Definitely good to use! Did find the super soft a little interesting to handle but still VERY usable. Would definitely recommend to anyone!

Fat, smooth and satisfying

Got the large and it's impressive. The smooth, fat tentacle goes in so easy but makes you work for every inch after that.

I love the super-subtle textures on this one; it's so fat that any real texture would just be too much, but this one is juuuuuust right.

The colors are beautiful, not that one sees much of them while it's in use, but it does look lovely and impressive on my toy shelf

Managed 23 inches so far, and very mnuch looking forward to hilting this thing.

And the suckers.... 🤤

You never go back

A really great toy to begin your depth training, with a profile that keeps things interesting from end to end. Go slow and progressively, though. The flexibility makes it tricky to handle, especially when fully lubed, but taking it all is particularly satisfying. I do think it could use a bit more work on the base for better suction cup use.

Deliciously squishy

A little thicker than expected, but deliciously squishy (in squishy soft). The suckers provide just enough texture to rub in all the right ways when pulling it out.

The rounded tip is much more comforable than a dagon, which is just a little bit pointy in some spots (but otherwise perfect).

I do wish the base had a bit more flare, though I still have work up to the point where that would be an issue.

I was very excited to receive this, and I am not disappointed

Wow! Exceeded my expectations!

So I've only used this baby twice so far, but good heavens! It's everything I was looking for and more.

I've only recently started exploring my needs and fantasies, and I've lowkey always had a thing for tentacles so my first fantasy toy just had to be one. I chose medium and it's perfect, the gradual increase in girth makes it super easy and comfortable to insert, and the texture feels amazing both internally and externally. I've never felt so full before, and god does it feel good to grind against it while thrusting, the orgasm I got on my second session with it was mind blowing.

I picked the ultra soft/squishy option and it is indeed a bit of a challenge to get the tip in but I was expecting it as I had read the previous reviews before ordering, and to be honest it doesn't bother me. It kind of feels like I'm dealing with the real thing lmao.

The material used is of exceptional quality, it's one of the best feeling toys I've ever had/used, and the colours are stunning, it's exactly what I was looking for! I'm so happy I found out about UC! I will definitely be looking into the other toys once I have the money, the one I got was worth every penny.
