This has been a great unit for the last couple weeks so far. I had no issues with tripping breakers or melting sockets, which is saying something because i'm running this on a circuit with a spacer heat, in an old house. The circuit mentioned cannot handle 2 space heaters, but runs this just fine somehow.Lastly, I noticed what might be the main gripe i see in reviews, which is that the unit doesn't get hot enough. What this is with mine is a simple mislabeling on the temperature control. Written is Centigrade, while what it actually does is Fahrenheit.I'd say that selling this to someone who doesn't know how to recognize heat output is a major failure, but for what the hardware can do its awesome.
