Great size for smaller rooms, office, bathroom, small bedrooms. Saves energy from the old 1500 watt heaters. Only issue I have is the feet. Two small metal fins plug into plastic feet. While assembling, the metal tended to bend. Since it is part of the heating unit, I feel a bend or crack or break will ruin the heater.

Safe and comfortable

Besides providing comfortable heat with no sound and with an internal thermostat, I chose this heater because of the superior safety factor. I replaced three baseboard heaters after reading reviews of the fire hazard they represent. The mechanism used in the Newair heater presents no such hazard and I can rest assured that I won't have a space heater fire!
Suits my need. The wattage allows me to use with solar generator while camping. Just enough heat to take the morning chill off in my small Motorhome kitchen.
I would recommend this to a friend!

Funny how that small heater heats a room and each time I walk down the hall it's warm as well.

Great new product!

Just what I expected! Meets my expectations perfectly. Compared to other space heaters (1000 - 1500 W) it works with 400 W - consumes way less energy. I use it in the bonus room that is above the garage and always a couple degrees colder that all the other rooms. The heater is small, noiseless, heats up fast and warms up the whole room in a couple hours. I placed it in front of the window, so it keeps away the cold from coming in. Now the room is nice and warm when my children come home from school. We love it!
I would recommend this to a friend!

We bought this little heater probably 10 years ago and it has been going stron ever since. We have concrete floors and my feet stay cold in the winter. This little heater keeps my toes toasty.
