At 3 speed it is heated so that it is impossible to hold the hand, cool thing, I took it to warm up the gel varnishes and Nelles in the cold period, when there is no light, I advise
Excellent product does keep Coffee at the temperature that it is at the time its placed on device will not warm something up from cold but maintains the temperature. really quick shipping from China to the US. Great transaction all around.
It's enough for warming tea but make sure you use a flat bottom cup
