I just bought this heater recently on a recommendation from my daughter. I was quite amazed when I plugged in the heater and it quickly heated up my large bedroom. I was so impressed that I immediately bought a second heater for my son. The heater has many safety Features, including automatic shut off as well as overheat protection. It was a great value. I have been impressed with Black & Decker since I bought a small rechargeable can opener back in the 90s. Their products have shown themselves to be reliable and long lasting. I am looking forward to many years of heat from this mighty little heater.
