I have had my DeLonghi heater for about a month, and so far it has been great. I use it for zone heating. I leave my home thermostat around 60 degrees, and the space heater in the room where I am working. The heater has a thermostat, so I am able to adjust the temperature up or down as needed. It has has an option to oscillate to move the heat more efficiently around the room. I haven't had my first power bill since I purchased the heater, but I hope it will have cut my bill! Design The handle on the back isn't deep enough to allow me to pick up the heater with one hand. Safety Stops when turned over.
