Mustard USB Cup Mug Warmer Coaster- Donut Freshly Baked (M11011B)

I was really excited about this because I wanted to use it for work. I love coffee but I have to microwave my cup all the time because I get busy and it gets cold, so I thought this would solve my problem while also looking cute on my desk. The pad heats up and gets pretty hot but it does NOT keep my coffee even remotely warm. I'm going to return it.

This product will not be purchased again, nor will it be recommended.

It got hot and kept my drink warm. I read these reviews staying it didn’t work but I had no problem with it.

Cute but doesn't work

Great whit elephant gift!

doesnt heat up very well

looks great, mot used yet as is an xmass prezzie

That dime size dot that heat up isn't hot at all and this thing couldn't keep 1 swallow of coffee in a cup warm.It does work nicely as a fingertip warmer though.

This product had good reviews and thought to buy it because it looked great and at a decent price. When I received it, the packaging and product was at a high standard. It was when i put it on to test it, it took a long time to get to its maximum heat. When it eventually got hot my drink didn't stay warm but went cold at normal rate. Although it was quite hot to touch it had no impact on my drink but warmed the bottom of my mug slightly. Very disappointed

Love this cup warmer, I use it to warm up my thick builder gels

I bought it for the office to keep my hot beverages hot, but it doesn’t really warm it up nor keep it warm. It is good looking but I kinda am desapointed. Plus it makes my desk very hot and i dont think you should let it run when you’re not around, it could burn your desk

Der Wärmer roch eine Weile mittelstark nach Gummi und leider hält er den Inhalt der Tasse nicht wirklich warm und erst recht nicht heiß. Schade.

j'ai reçu mon chauffe tasse et bien devinez??? ça fait deux heures qu'il est branché ! et vous savez quoi???il ne chauffe pas mais rien il est froid on en gaspille du fric avec ces gadgets qui marchent jamais! ou tombent en panne ! amazon!!!! vérifiez vos vendeurs ce n'est pas sérieux tout ça!
