I’ve been happy with my heater so far.  The slim design is perfect to not obstruct walkway.  I’ve used on my patio when sitting outside at night and it gives the perfect amount of heat for the area.  It’s very quiet, so we don’t have to raise our voices to hear each other.  I have found that when the fans are on, it’s much louder.  At this time, I don’t have a need to mount to wall, but love that option.  It’s very sleek and a perfect compliment to any room.
