If you have a large onahole that the average warmer can't reach, this is probably what you are looking for. It is also nicely temperature controlled. None of my onaholes melted on me, yet. So that's a plus.
The few downsides I can think of are that the UV light cannot be turned off. So expect your onahole to grow a little bit purple at the end. A quick search also shows that UVC can damage plastic. But as far as I can tell, the effect isn't obvious with the few use I had so far. The casing of the warmer also is a little bit rough. It is fairly minor but I can see some onahole with more elaborate interior getting caught on it and get damage over a few dozen uses.
Last but not least, the green light that tells you the warmer is at temperature only tells you the warmer is warm. Your onahole can largely be stone cold at the first green light. So keep that in mind while using it.

I might have got a defective one but if it happens to mine, it can happen to yours.
The item is functional. The button does have a stay-on lock/toggle if you press it down completely. So no need to hold it down the whole time.
The problem with this item is that whenever I put the battery in and if it is not turned on after a few minutes, the battery itself starts heating up, which indicate a possible short circuit somewhere (yes I looked up the possibilities of it being otherwise but short circuit is most likely). This has so far happened to 3 out of 3 of my own batteries that functioned completely fine in remotes. 1 out of 3 of those batteries got so overheated that it spilled battery acid/content all over the place a few minutes after I removed it from the rotar. I do have to mention the battery doesn't seem to heat up if you turn the rotar on but would otherwise. So just keep that in mind if you do buy this.

Not much to say except it works. It is a little bit pricy compared to Onatsuyu as this bottle is half the size of that.

Feeling-wise, it is a little bit thicker than Onatsuyu. It should work well with some low-stimulus onahole where you want to enhance the stimulation.

Overall, it is something good to have in the back of your drawer in case you wanna switch things up a bit. But I will stick with the more economic options out there. 4.5 stars and rounded up to 5.

Disclaimer: My member is about 13cm or 5.12 inches. Experience may vary based on your exact dimensions. As per all the onaholes of this size and thickness, review is based on getting all the air out of it. Otherwise, lower it to 3 stars for lack of stimulation in the front half.

I ordered this as pre-order and gave it 3-4 use so far. It is holding up okay. No visible tear and wear yet.

First half of the onahole is actually not particularly stimulating even with the air removed. It feels alright but the combination between the surface structure and the texture just feels a little bit lacking.

The gimmick itself is not too tight. For comparison, this is probably less tight than the hymen structure you can find in Sujiman Kupa Lolinco. It is also not particularly stimulating.

The deepest bit of the hole practically have no stimulation for me. But as I said in the disclaimer, my member is only 13cm while the internal length is probably in the 14cm or 14.5 cm range. I can't reach all the way in unless I push it down a little bit. So your experience may be different.

Suction-wise, it provide a pretty good grip similar to Seventeen Bordeaux.

Overall, this onahole is okay. Definitely would not suggest this as a first. Instead, I would suggest Seventeen Bordeaux or Seventeen Bordeaux soft if you are looking for suction. However, if you are looking for something different, this might be the toy for you.

Got this doll a few weeks ago, stuffed it with some polyfil. For reference, it used up about 1/3 to 1/2 of a 5 pound box. I tested it out around 4-5 times and came to the following conclusion:

1) TOMAX Venus real is probably the largest (in diameter) that you can fit in there
The hole itself, along with the velcro and the tie string, holds any sleeves you have up to the TOMAX-Venus-real size. The hold is really secured even if the sleeve you are using is slightly bit smaller.

2) The zipper on the back, while it cannot be hidden, does not cause much trouble.

3) The sleeve secure mechanism, while as good as noted in 1), is really difficult to setup if your sleeve is as big as the Venus real.
I had to battle with it for at least 5 minutes each time to get the sleeve in there because the velcro would sometimes caught itself while your sleeve is halfway in but not fully. I tested this out again with smaller sleeves (in my case, TOMAX Lilith Uterus) and the whole process is much easier. So be advised that if you plan on using some thicker sleeves, you might have trouble with the set up.

4) hugging-wise, body pillow is still better than this doll

5) while I don't have to hide the doll since I got it, it would be extremely easy to hide if needed. Just pull the filling out and the casing itself is no thicker than a T-shirt. This would be perfect for anyone who need to hide their toy while still want a doll experience.

6) works amazingly well with VR but that's probably any doll in general
