Junk!!
Bought it yesterday and I've used it about an hour maybe. Shuts off for no reason. The fan is so loud you can hear it down the driveway with the garage shut. Filling it with kerosene is a pain. The garage smells like kerosene after 3 minutes of run time. I paint cars in the garage on the side and usually get a couple years out of my heaters. I'll be surprised if this one makes it a week! At least it will match my DeWalt 60 gallon compressor, that's a piece of junk also!
Worth the price! Especially during the below temps
Great heater heats my shop up in no time
