We recently moved into a new house and for some reason our master bedroom is colder than the rest of the house. We thought this would be a good option. Its installation onto the wall was fairly easy...it had to line up just so by a plug. It is louder  my husband and I expected, but very effective. We usually sleep with white noise so the heater’s loudness has not woken us up at all. We really needed it to take the edge off that room compared to the rest of the house, and it has done a fine job of it so far. It has two levels of power, and most times it has kicked on to heat the room, it has been only half power and done its job. Glad to have it as winter approaches!
