So far, so good. Bought one in the smaller and one in the medium size. Move air well and are very quiet. The fan can spin both clock-wise and counter-clockwise to move hot air down and cold air up, depending on your season. Minus 1 star because the light isn’t as bright as I would like and the dimmer feature is a bit awkward to operate. Would’ve much preferred a sliding dimmer than a large green button you have to hold down as it cycles through dim levels and try to catch it at the brightest point before it drops back to the lowest light level.
