So far, five years and counting for my cheap little stove. I had to replace a high limit snap switch that I bought from Graingers. Other than removing the fans, lubing and cleaning them, I haven't had any other issues. I think I'll be drilling a hole on the side of the Horseshoe to clean that out in the near future but I think the leaf blower trick has kept it relatively clean. A few burnpot mods recommended by Dexter has helped tremendously!
