“ Wish I had read the reviews before I bought the M55 Enviro. We have had wood stoves & then bought this model. Same problems as stated in other comments. Cleaned often & also by the company we bought it from. Auger doesn't turn. Pellets build up. When it runs for awhile & shuts off. Electric panel quit & then a season later runs on manual. Of course out of warrantee. So stuck with it? For a multi fuel stove the pellets burn poorly & with a lot of buildup even with proper cleaning.
