The bathroom fan is easy to mount and that does not run very quietly, but has a decent performance. The louver opens and closes reliably, so that the return flow of cold air is prevented, and the delay time can be adjusted. A small LED indicates if, the closing is closed. As soon as the indicator light goes out, the delay time starts. Decisive for the purchase of the fan was the reasonable price for me, especially since the motor ball bearings is available.
