The fact that it can warm or chill your drink is new. IIRC they could only chill them before. The thing is I've read a review on this and it doesn't work very well with cans because they only have a small ring that actually makes contact with the plate. It works better if you pour your drink into a cup with a flat bottom. Makes sense. I've always thought about getting one but as of now I haven't had problems finding a lot more useful things to spend my money on.
