Solid machine for this price range. Easy to operate and heat goes up fast.I use it to heat an uninsulated garage(c.18m2) and it performs fairly well. Lowest temperature that I tested the heater was around -23 celsius and it still started up nice and quick. Haven't had a problem with it in these 15-20 hours of operation time.I did not manage to get the remote controller to work but the reason for it could have been my own lack of patience at the moment.
