Heater works fine and is as described, but the control panel is difficult to use and the instructions could be improved.
There is no filter for the fuel inside, and I had to buy one and insert it myself--which was not a difficult job. Having a portable heatrr with the exhaust coming out of the bottom means it has to be mounted on a wooden or metal frame to get enough clearance to put a bend in the pipe to exit the exhaust other than through a vehicle's floor.
The biggest problem is the control panel. The Vevor diesel heater I previously bought for my camper has a display panel far easier to use.
