Review on Exhaust fan Soler & Palau SILENT-100 CZ, Silver 8 W by Stanislaw Stanislaw ᠌

This one is my second. The first worked for more than 5 years almost without shutting down. Sucked great. smoked in the toilet, the smell did not spread throughout the house. After the old one broke down, I tried several variants of domestic and Belarusian ones - everything was not right. Even from scratch they worse. Bought again silent. It works better than the Belarusian ones, but worse than the first fan. I'm afraid that the ventilation shaft is clogged. I read in the reviews that someone managed to disemble this model to the engine - I was not able to do this, otherwise I would not have thrown the first one away, but simply fixed it. Belarusian to wash dismantled to the ground without problems.
