Does a good job
Review by a stick
It does a good job at warming up the toy. Very easy to use, but I'm taking extra precautions by putting a towel around everything because I'm kind of scared of the UV light.

Simple and effective
Review by Eyebeme

Although it is very short, heat is less limited and UV light even less than that. A clever idea and it works(the heat, at least, but the science does support the sterilisation, also)

Great product
Review by M
The warmer greatly enhances the experience, while offering sterilization. However it is not perfect. I wish it would heat up the toy slightly more, because the warmth quickly goes away when you start using it. It still feels much better than using a cold toy, so I think it is still a must-have product. I highly recommend it.

A warm Onahole is just better
Review by Akali

The KYO Steri Warmer does what the name implies, it warms and sterilizes your onahole. A warm onahole just feels better than using it as is. Of course, the UV light does not kill all germs and bacteria, but it still helps. I would still use a spray or a proper toy sterilizer just to be safe.

My new favourite
Review by r/Onaholes2 Reddit
Here are some additional pictures to the ones i'll be referring to within the review: https://imgur.com/a/OV8R1HH
So this device is called the KYO Steri Warmer. An onahole warmer is an item that every onahole user should be familiar with.Warming up your onahole before use makes it feel really close to reality and also more stimulating.
But this device also has another functionality, which is disinfecting your toy via UV-C light (this is obviously no replacement for your regular toy cleaning).
UV-C rays have the ability to kill mold, germs and even viruses. There are many such devices for disinfecting women's toys already, but as far as I know, this is the first one for male sex toys.
The way it works is by having three UV-light-emitting LEDs on each side and a heating strip (see pictures). Unfortunately, I actually don't have a microbiological laboratory, so I cannot test its sterilizing capabilities. But it is a proven concept, so it should be really effective in practice.Just be careful not to look into the LEDs, as this will hurt your eyes.
But how good is its heating functionality compared to its competitors?
The competing products I tested it against were a cheap unbranded heating rod and a "DMM"-branded one that was a little more expensive.
Here are the results after setting up a timer for 5 minutes:
• -The unbranded heating rod was the coldest of the bunch and also had an uneven distribution of heat, being completely cold around the tip.
• -"DMM" onahole heater was the hottest, but it kept getting hotter still. This could melt your onaholes after some time. I once left a warmer like this in my fleshlight for about an hour, and it completely ruined the toy, so be warned!
• -The KYO Steri Warmer on the other hand, automatically turned itself off after heating the toy perfectly within only 5 minutes.
The ability to stand straight up thanks to its rubber base also makes this the more convenient option for me, as you can start using your toy immediately without having to deal with putting a lubed-up stick somewhere.

The only downside I found is its length, at 12.5 cm, it might be too short to reach the end of some longer onahole tunnels. 12.5cm is not as bad as it sounds though, because the heat also transfers within the material, so its heating capabilities are a little bit longer than its physical length.
The other rods are not much longer, but the lack of a base also means they can be fully inserted at least.
Overall, I really like this new heater; it's the best one I have used so far!

Pros and Cons:
+nice build quality
+innovate 2 in 1 functionality
+overheating protection
+fast heat up time
+convenient base

-could be a bit too short for really long onaholes

Works but don't feel a huge difference
Review by Sweedee

Does what it should, after a few minutes it turns off automatically and the onahole gets pretty warm. However i dont really feel a huge difference in terms of warmth when using it. Maybe my pp is just temperature insensitive.

Works very well but a little bit short
Review by Peet_14
As the title says the Warmer works really well. The temperature is great for the onaholes and the automatic heatswitch works perfectly.

The only thing ist that the Warmer is pretty short so you can't reach the top of some longer onas

Review by Daniel
Um einiges besser als der KYO Onahole-Wärmer, den ich vorher benutzt habe,
Wärmt gleichmäßig und schnell auf. Leider etwas kurz von der Länge finde ich, aber dürfte für die meisten Onaholes passen.

works great
Review by nawid
it warms toys up within 5-15 minutes depending on the toy size. works great and even if it is a bit smaller than the toy hole it still warms it up completely. bonus points you don't have to worry about it melting the toy. i left one in it for 30-45 minutes and because it turns itself of the toy was not damaged.

Ideale warmer!
Review by Gilles
De KYO Steri Warmer doet exact wat je ervan verwacht. Breng de warmer aan in de onahole die je wil gebruiken, sluit het usb-uiteinde aan, wacht enkele minuten en geniet van je heerlijk warme onahole! Het desinfecterende Uv-licht is ook een zeer leuke bonus voor diegenen met smetvrees onder ons (zoals ik).
