Good, Slow, and safe

Takes 30 minutes to warm up an onahole. While the wait can be annoying sometimes, it heating up so slowly means it's safe in case you forget it by a few minutes.

Pretty hot stuff

I left this thing on for about an hour and it sure does get piping hot. It does warn you not to turn it on for too long but the heating system works a bit too well sometimes to the point it makes me worry for damages.

Decent Heating Solution

Takes a while to heat up, but the material is good and the USB port has a cap which allows you to wash it more easily. Might get a bit too hot if you leave it in for more than 30 mins, as I have learned using the Tenga Flip 0. Overall, still one of the better heating solutions out there.

Reliable

Worked well every time I've used it. Hasn't overheated. Price could have been cheaper though since it really isn't that complicated of a product.

hot hot HOT !

I love it, it's perfect to warm your toys, just leave it warming up for about 10-15 minutes depending on the tightness of the toy and your toy will improve it's sensation tenfold.

10/10 warming tool before a session

Living in Norway, it can get really fucking cold at night. But only during the winter. And early spring. And late autumn. And if you have an onahole next to you, all lubed up and ready to go, you'll find yourself getting into something relatively cold. And where's the realism in that. Now, first time I used this was with the Sakura Kirishima Meiki and sure enough, it warmed up the hole pretty decently. Since then, I have only gone once without using this in an onahole before my session with said onahole. Second time I used it was with the Naked Sanctuary Raw. And here I made the semi-mistake of waiting too long before getting down to business. You see, giving the heating system about 15 minutes or so before starting your session should be enough to warm up any onahole. I gave it a little (a lot) more than that. I entered the onahole and sort of hurt my dick. Like getting into a bathtub filled with hot water and you're going in butt first (and in the process scorch your nutsack). It was pretty much like that. But the warmth really made it worth it. In all: don't leave the heating system in for too long, unless you want your dick to get burned a little.

Works like a charm!

The Onahole Heating System has provided a unique experience in my frequent usage of Onaholes. By providing the options to heat up it has really changed my approaches. Moreover the convenience of how handy this tool is is extremely redeeming as all it takes is a plug of the USB. While the lid of the USB outlet at times is very loose and can come off, it has lasted for a long time and still functions as normal. Great product for people seeking a different experience with Onaholes.

Love The Lightning

It heats up fast and has a decent size. Compared to the chinese ones this is a completely different quality product. Also have to say I really love the red light. I didn't think much about it when I ordered, but now I think it's an important part of the experience. Sets a great mood if you are in the dark.

Does its job

Not much to say about this one other than it does its job at heating up onaholes for usage. It usually takes roughly 15 minutes to heat up onaholes to a good temperature from my experience. Be careful to not let it inside for too long though because it can get too hot which could not only damage the onahole but your penis aswell.

It does what it's job

Well it works well with some onaholes but not all of them, for example for: Student council president and Virgin Age Admission Hard Version, it doesn't works very well, but with The Mouth of Truth and Sujiman Kupa Lolinco Virgo it does an amazing job and it really enchance the overall experience taking it to another level of pleasure. Easy to use, it takes around 5-10m to heat the entire onahole, it works flawless with soft, regular type (from Magic Eyes) onaholes, not suited for hard type, and difficult to use on very tight onaholes.

Could be faster, but its good, and you should have it

It does it's job so I have not complains, and this type of items are essencials to have a good experience In the other reviews everyone says that you need to use lube on it, so I do that and take about 10-20 min to warm up, so it's good. And i've seen that the other warmers have the cable attached, so thats has a pro over those ones.

Never worked

I got this more expensive one cause i wanted one that worked but this never even turned on, tried it for a few time for more than 30 minutes but didn't feel any heat and from multiple different power sources also. I might be in the minority here but mine didn't work at all and i'm kinda pissed.

Best warmer I've used yet

This warms up faster, is more durable, and has more usable length than the Rends version. The extra cost is very much worth it. The detachable usb cable is a huge plus and allows for a lot of convenience. It's long enough to warm some of the longer onaholes I had and warms up very nice and even. The biggest problem I had with the Rends warmers is that the cap where the cable is connected would come off and pull the warming element right out with it due to lube loosening it. The one doesn't have that problem. Also something to note...the box advertises "mobile battery" on the side but this doesn't mean it has a battery integrated, it means that you can use this device with a usb battery pack for mobile warming away from a computer or a outlet (which were the other two advertised methods of power source). Not sure why they didn't just say that, but it is confusing/misleading due to loan word meaning in Japanese.

Expensive but very good compared to other products!

Heats good an onahole in 15 mins with air conditioner on, heats the whole rod perfectly, not like other products.. But to wait 15 mins is a little long, I wish there was something stronger with own power supply because USB output is just 500mA 2.5W, very weak for a heater generally.

Well it works?

Honestly, I like the idea of beeing able to warm up your onahole. But maybe I´m stupid or the heater is broken, but it takes 20-30min to really warm the onahole up. I rarely use it because it takes to long and I fear that I´ll forget it one day, burn up my onahole and the house with it. What I like to use it for is as a Dildo in the ass, cause the warmth transfers way faster and feels kinda stimulating in there

Good Quality Product

The product works great in warming all of my onaholes! So far it has lasted far longer and is more reliable then the Rends usb warmer. The detachable cable is great allowing for replacement if necessary and a possibility of a longer cable. The cap however is untrustworthy, never seeming to create a good seal. As others have wrote, I don't recommend submerging in water. It does give me some confidence when just rinsing the outside of the warmer as the cap seems to protect it from random splashes of water. The product description is slightly misleading. It states it has a mobile battery, but I am unsure of its use. As far as I can tell, it does not heat up unless the warmer is plugged in. Overall, if you like warm onaholes, this is a good buy, it is dependable and the product lasts.

Good warmer

This warmer was supposed to replace my previous one which still works but doesn't have a detachable cable, is shorter and warms up slightly slower. I like the detachable micro USB cable although by now Type C would be more appropriate. The increased length unfortunately doesn't play in my favor since my onaholes are on the small side and the warmer starts heating up from the "bottom" (where the cable is connected). Therefore, it's not much faster than my previous one even though I can feel it heating up quickly at the bottom. There's a rubber plug to cover the connector but it barely stays in place and while it may seem water-proof at first, I would definitely not recommend submerging it in water.

Really good for the price

Perhaps the biggest selling point of this warmer is the fact that it has a detachable usb cable, it seems that’s the biggest weak point of warmers. As long as you take proper care of it, it should last a long time. The texture is also quite nice, it also comes with a usb cable, in case you don’t have usb to micro usb 2.0. A warning to first time users. You must be careful not to leave it inside too long, it happened once to me. I left it too long and it onahole got a damaged due to that. I would say no more than 30-40 mins with some occasional checking. That aside, you must find that sweet spot, so as to not damage your onahole, but still get a nice and comfortable warm feeling inside. All in all though, I would highly recommend this warmer over the cheaper ones, it’s defintely worth that little extra money for what you get.

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.
