The stove is well constructed and feels solid. The fan is removable and looks to be a standard computer fan for easy replacing. I tested with both small sticks and wood pellets. It worked very well, with both. The outer didn't even get hot which is a great safety feature.
My only criticism is the two speed control a variable speed would be better.
Excellent build quality . Works very well not the smallest but still quite light .would highly recommend getting a USB stepped controller as the standard 2 speed one provided could be better the lowest setting I feel is still to fast ..
