Warmer does the job great. It feels sturdy and warms reasonably fast. It is a bit pricey though

Best warmer I've used
I've used 3 other warmers and this is the best one. You really seem to get what you pay for.

The outer shell is made of a non-brittle plastic with a nice soft finish to it. It's long enough that it never has a problem reaching all the way inside.

On one end there's the red cap that's supposed to protect the USB port. I wouldn't trust it enough to submerge that end but it works great when just rinsing. If the cap is open there's a risk of it detaching but it's easy to put back.

Now, unlike most heaters this one has a detachable cable.
The cable is often a weak point. It's often too short and stress/bending on the cable can cause the thing to die.
This warmer doesn't have that issue. The included cable isn't too shabby and USB A to micro B cables are sold everywhere if you want a new or longer one.

When it comes to heating it works fairly quickly. I've found that it can handle a 2 Amp current well (like from a modern phone charger) and it can halve the time it takes to heat stuff to a snugly temperature compared to the standard 0.5 Amps of some USB ports.
I tend to leave it in for 5 to 15 minutes depending on the size of the toy and how hot I want it. I have left it longer, up to 30 minutes, and haven't noticed anything burning or melting.

Pros: Detachable cable, warms quickly, good quality - will probably last years
Cons: Price is a bit higher, cap end doesn't seem like it would be 100% water proof - just don't submerge that end and it'll be fine

A bit confused, but overall I'm very happy with it!
I've owned a "Rends USB Onahole Warmer" for the longest time which recently stopped working and I decided to get a replacement. I saw this one and it seemed to be a step up from the Rends and while it definitely is of better quality, I am a bit confused as to it's features.

+ The sturdy detachable cable feels like it would run into less issues than cheaper warmers where the cable is fused directly into the heating unit. In general a sturdier construction and higher quality product.

+ Does the job just fine. If I am not mistaken it heats up a lot quicker than my old Rends, too.

- Does not work with the cable detached as expected. The product description that makes mention of "mobile battery" makes it sound as if you could charge it with the cable and then it would keep warming the hole even with the cable removed - this is not the case as it cools down quickly at that point.

Maybe I'm just missing something (as I don't read Japanese i don't understand the instructions on the box). But overall I am happy with the purchase as it seems like an upgrade over the cheaper warmers.
