As mentioned in previous comments, it is not silent and even worse, the plastics it has for the supposed backflow hit against each other and there is a continuous rattling sound. I will remove them and put in an extra backflow. A metal one that I already have and tested does not have the power to open it, so I need to find another one. What a shame. On the plus side, it releases a good amount of air and has a nice design. Cheers.

In no way is it QUIET, especially when you have to listen to it for more than 5 minutes. We made a big mistake and connected it to work together with the ceiling lights. Now I don't want to turn on the lights so I don't have to listen to it. We renovated our bathroom and needed several things, and buying this ventilation was the only (fortunately) MISTAKE, unfortunately the bathroom doesn't have a window and ventilation is necessary. Wherever we asked, they spoke highly of it and we believed them, trusted them, and now we're banging our heads because it's incredibly annoying to constantly hear this noise. DO NOT buy it, I believe that the 26 dB they mention in the product's specifications is a big lie. If it's like this at 26 dB, then how do the others we saw at 45 dB sound? Like a compressor? We lost 75 Euros, we lost our peace and gained a lot of noise, the previous reviewers who say that the reverse can be heard are right, it's a small film-membrane that when the ventilation is running, it also sounds annoyingly!! The WORST PURCHASE I MADE!!!

Only for its appearance it is worth it. Overall, it doesn't do a very good job. It makes a lot of noise! You can't call it silent even as a joke. I see that the price has also increased, unjustifiably I would say. If I need to change a fan, I will probably go for another one. The 2 stars are only for the design.

It does its job but with "noise" ..... I tried other much more economical ones and the difference is very small

I had it for 3 years (then I switched to a similar product from the same company and I was satisfied). You can't call it quiet in any case. If you have it constantly on inside the house, it gets on your nerves. Definitely quieter than most other cheap alternatives though. It has a decent air displacement ability, enough for very small bathrooms. The built-in reverse is a joke - two plastic films that don't close well when it's off and sometimes make extra noise because they move when it's on.

It is not as quiet as described. With my own dB meter, it showed an average of 45. I'm not sure if its suction power is 175 cubic meters. There is not much difference compared to an Aliberti I had with 95 cubic meters. Definitely not worth the €46 I bought it for. The only positive thing is its aesthetics
