Works well, good value

I bought a cheap mug warmer from a Chinese company and it only kept my tea barely above room temperature. This one, however, works very well and maintains the perfect temperature. The photo on the Teasmith website shows a dark colored warmer, but the one I received is white. Not a big problem. One thing I don't like is that the on/off switch is on the cord, not on the unit itself. I want the cord out of the way so I have the warmer placed on my desk so that the cord goes back behind the desk, and therefore the switch is hard to reach. So the design of the warmer is not the best, but it works well and is very inexpensive compared to others I have seen.
