Buy at your own risk!
Had three these since the middle of December. Just tonight, got home, relaxed in the living room and starting smelling a burning smell. Well it was the unit that was failing. Luckily we were home or who knows what could have happened. Have to replace an outlet now also as there is some burn damage to it.
