Practical fan for improvement

This fan does its job in a small bathroom. An existing duct was not sufficient to carry away the moist air. Therefore, I opted for the installation of a W-style 100 in this slot. The fan can be heard clearly because there is quieter. But the efficiency is already good. Studded walls belong to about 12 - 15 minutes of the past.
The electrical connection is given at the 12 clock position through an opening above the fan. But since I could not place lead here, I had the fan befestitgen vice versa, so that the lettering and the LED are now located above, so standing on your head. It would be nice if the specified cable channel in the device the choice between cable entry would have the top and bottom.
But for the price it is inexpensive in the true sense of the word.
