We originally had to return our first shipment because the heater was damaged during shipment. Upon receiving the second shipment, one of the screw holes did not match up to the legs of the stove. We also noticed factory assembly of the heater was sub par at best. Two screws were found loose and another screw was screwed through the bottom plate. I gave this unit two stars because the heater is working nicely and heating our bedroom up nicely.
