It works. It just doesn't push air like I was hoping.

This is a good solution for improving the heat distribution of heaters like the Mr. Heater Portable Buddy. Propane-fueled radiant heaters tend to lose a fair amount of heat to convection that just drifts upwards (indoors) or gets blown away by the wind (outdoors), which makes them kind of inefficient.

This fan allows that otherwise lost heat to conduct through the aluminum extrusion, which creates a temperature gradient that powers the fan, which draws the heat across the extrusion towards you - or at least into the room in such a way that it distributes much more evenly, rather than drifting upwards towards the ceiling above your head, where it doesn't do much good.

Search YouTube for some examples of people attaching these stove fans to Mr. Heater Buddy models. It's easy to do with a bit of wire, twist ties, plastic ties, or something like that. It makes a noticeable difference to the amount of useful heat you get out a given amount of propane. Since this fan only has one moving part, it should basically last forever, and it should pay for itself eventually in saved gas while it keeps you more comfortable all the while.

Only minor glitch was that the "motor" shaft was very slightly bent on one of the two I bought. It didn't seem to affect functionality at all - the blades still spun freely - but I didn't want it to create any noise or uneven wear over time, so I used pliers to coax it back into alignment. It was a 15-second fix and seems good as new. It's packaged very well but is perhaps a little overly snug, which might have just torqued the fan blades a bit when it was inserted at the factory.

hard to believe but it works great and it helps spread the heat, a very good investment.

The media could not be loaded. Works great! I positioned the fan on top of my pellet stove heater as directed. The fan spins quietly and fast enough to move the heat into the room. Very cool device. I am satisfied with this purchase. The package includes a nifty magnetic temperature gauge and a Lil Buddy propane heater fan attachment bracket. I haven't tried that yet but will next time on my boat.

We bought two. One came with out of balance blades, quickly replaced and resolved. These are quiet and they really do a nice job moving the heat. They are small, as most of these are, so two of them help disperse a large stove and heating area. Great value purchased during prime days!
