Bests & Worsts Reviews from Amazon

Tried multiple cup warmers, ranging from 10W up to 24W. This one certainly, defiantly not 24W. I had a brand-less cup warmer with 24W power and had the cup nearly boiling-hot. You can almost cook on it. This one? Not even close. And yes, both are in the exact same environment. The very same cup (same one, not alike it), same room, same tea and exactly same location on the desk. Also when you rise the cup to sip from it, the numbering-light keeps flashing constantly until you put back the cup, apparently this is a new feature (the induction switch) which is utterly annoying, if only I can switch it off or get rid of it. That being said, this cup warmer is way too expensive for such average performance. Won't recommend. Update: I have purchased an 18W cup warmer, the new one is CERTAINLY more powerful than Cosori's. I only wish I could return it, sadly impossible.
