Bought this for my Husband for a little present for his birthday. It turns out to be a useful little gadget. By itself it's not enough to keep a cup of tea 'just made' hot, but it does keep it pleasantly warm, extending the time you have to drink up. [which is rather on the useful side if you're working on the computer and forget about it!] At no time does the plate itself get too hot to touch so no need to worry about accidentally putting your hand on it.
