### 5/5 — Believe it

*2026-07-28*

For some years, I’ve been a proponent of very hot water on a bite to overwhelm the itch. It works, but it’s sometimes difficult to run water on just the bite (or bites), and it can take a minute for the water to warm up, assuming you have access to hot water at any given moment. This works SO much better! It’s quick, dry, precise, and easy to carry with you wherever you go. The interface is so easy, and the relief is instantaneous. This product is THE perfect bite relief solution. Amaze amaze amaze

### 5/5 — Works Perfectly

*2026-07-20*

Doubter here! 👋 
I didn’t see how this could possibly work, but in reading the reviews it seemed that it works for everyone! And being inexpensive I decided to try it. IT WORKS. The heat neutralizes the itch and boom, it’s gone. The app is as easy to use as possible and it literally opens when you insert the device into your phone charge port. The heat from the device isn’t bad (to me!). 6 seconds of heat and the itch is gone. I’d recommend this to anyone , especially my people who become a buffet for mosquitoes when they go outside. 
If you’re on the fence about this device but you hate suffering from itchy bug bites, this is for you. 10/10

### 5/5 — Best thing for mosquito bites period

*2026-06-20, version 2.8.1*

I can’t recommend this enough!!! I use it as soon as I feel I’ve been bitten and the bites literally disappear. Mosquitoes love me but with this little device I I don’t even care. No more itching and scratiching!!!

### 5/5 — Works awesome!

*2026-06-17, version 2.8.1*

This product works great and is so cheap compared to the amount itch cream, you would have to get instead.

### 5/5 — Четко работает!

*2026-06-01, version 2.8.1*

Удивительно, но это работает на 5+

### 5/5 — ライターやお線香はもう使わない

*2026-05-28*

熱いのあてれば痒みは止まるのに、ちょうど良いものがなくて、ずっとライターの金属部分を火で炙ったものや、お線香で代用してきましたが、もう必要ないです。コレ最高！

### 5/5 — Sehr wirksam

*2026-05-23*

Ich habe dieses Gerät zum ersten Mal vor ein paar Jahren benutzt und nach einem kurzen Schock über die Methodik habe ich mich sehr mit dem Konzept angefreundet. Tatsächlich ist der Heat it sehr viel weniger Aufwand als ein Gel zu kaufen und aufzubrauchen, weil er schnell und unkompliziert funktioniert. Auch die App ist sehr einfach gestaltet und aufgebaut und einfach zu bedienen. 
Ich empfehle dieses Tool auf jeden Fall an alle weiter.

### 5/5 — Works

*2026-05-15, version 2.8.1*

I literally walk around asking people if they have a mosquito bite so I can show them this

### 5/5 — Like a really good scratch without leaving any marks

*2026-05-06*

It doesn’t make the bite go away for me, but it’s like one big scratch tha makes me not want to scratch it for a couple hours. It’s stopped me from scratching so much that I leave a scratch or a scar. That’s worth it for me. Note, I’m not using it on mosquito bites. I’m using it on what I think are mite bites and a couple hours after the bite, not immediately. And it’s working on those, I could see it working better if maybe I used it immediately and on different kinds of bites.

### 5/5 — Pretty fantastic

*2026-04-29, version 2.8.1*

So it works remarkably well. I’m at a loss for words.
