Bought one of these a few years ago! Actually a good solid product. Stove itself is UL certified, pellet hopper is not. Burnt many a night with pellet hopper, its great idea, fuel gets fed by gravity. BUT, had a few puff backs, caught the pellet feeder tub on fire, probably user mistake, but still not UL listed, Still scares me about having your fuel source right above your fire. Going to try again very soon without the pellet hopper and try just wood.
