They're the same as in the photo. But they don't heat. You have to have the Cup too much to keep something warm. I want them back.

This is really nice. Now I can drink my tea hours with good heat. So I tried it today it looks really well. Recommend the seller.

I get SUPER well the USB heater devices and I tested them and they work the 3 that arrived I recommend.

The goods came quickly. Everything works. Great thing. Thank you seller.

Good product according to announced fast shipping from China to Spain
