Query: Attractive and well constructed

What first got my attention was the looks. The unit seems very well constructed and the chrome and black are very attractive... Pictures don't due it justice. Second was the digital temperature read out. The controls are easy to use. Setting the temp, time it stays on and heat output level is a snap. The unit heats up quickly and does a nice job of keeping a 15x20 room warm. I highly recommend it.
