Query: do not buy this poorly designed hotplate

I have no idea how this got more than 3-stars on Amazon unless people just have not used a good hotplate before.I bought this to replace the 10-year old hotplate I got at walmart for ten dollars that finally quit working after using it a couple times a week.Unlike the old one which had a compact base of solid insulating plastic, this one has a huge metal base that gets glowing hot and cannot be touched or moved even after the burner has been off for a minute.It also has the "china-made chemical smell" when used for the first time so I am sure there are some fumes burning off that are probably unhealthy.The burner itself is slightly warped and does not make full contact with a flat pot so there is wasted energy. The knob is also warped and wobbles when it's turned.This is ridiculously poor design, even for an inexpensive item. I'd return it if I had not used it. Instead I will toss it in the closet and search for a better one.
