Query: Hot Coffee

This is the 4th mugwarmer that I have bought - still using the other 3 in different places. Had a hard time trying to find one in the stores, so I was thankful to find one on Amazon.com. I selected this one because it was a good price and seemed more substantial than the others. So far it works great - no complaints at all. My other mugwarmers are white. I like the black color because it seems to blend better with my nice wooden office desk. I would recommend it!
