Smart Thermostatic Coaster Suitable for Home and Office Suitable for Hot Coffee Tea Milk Water Portable and Waterproof

Absolute useless junk. A cup of water "heated" to a barely warm state for a whole hour, after an hour the smell of burnt plastic from the body of this so-called stand was all over the kitchen, I unplugged it to avoid problems, but the water in the cup remained barely lukewarm. Money thrown away! Don't buy this toy crap! In the microwave, the same volume of water in a cup will heat to boiling in 25 seconds! But this crap didn't heat it even to +40* in an hour. But the smell of burnt plastic (or internal wiring) was all over the kitchen! I won't risk turning it on a second time, it's easier to throw it away! Don't fall for the description and advertising! Absolute crap!
