5 stars considering its price. Relatively quiet, it has a built-in flap that works only in a horizontal position. Time will tell its durability.

Very good! 1 month of operation and it is quite silent and at the same time very powerful.
It doesn't fit entirely into the pipe because the power cable sticks out.

Update: 1 year of operation without any problem!

I use it with a timer four times a day since the day I got it and it works great

In continuous use, several hours a day, from the third day it has started making noise. I don't know how much longer it will last...

Kids, it is very good and almost silent. I installed it easily by myself and it has been eight months in a windowless bathroom with full humidity and it still holds up. The previous one lasted nine months due to humidity

Relatively quiet and extremely effective for a toilet of approximately 30 cubic meters. Especially for its price, excellent. I would definitely choose it again.

Very good, I have it to supply the external panel of the fireplace with air. With the glass closed, in a few minutes you start taking off clothes from above you. It has a large and fast air capacity. For its price, it is excellent!
