I purchased all three of these fans, and I hung one of them from the ceiling in the bathroom. During the procedure, it was discovered that the engine was not fixed in the housing in the typical manner. As a consequence, when the engine was turned on, the blades began to hit the walls of the housing, which caused the engine to turn off automatically. I don't know how long this method will hold up, but the ceilings managed to fix the motor in one of the fans with the assistance of glue. However, because I didn't want to go through the trouble of fixing the other two fans, I had to issue refunds. Given the overwhelming number of favorable responses, it's possible that this is a marriage. When mounted, the interior of the fan has an unremarkable appearance; the terminals are secured with screws; the execution is straightforward; therefore, it is unclear as to why it is so expensive.
