It is not silent nor annoying. I placed it on an exterior wall and if it is windy outside, the fan turns.

Easy installation. The lid is screwless. Mesh for cockroaches. Sucks powerfully. No noise. Only the air passing through the grilles can be heard. Purchased a few months ago.

The first one lasted about 5 years. Now I bought the second one. Silent without rattling and powerful motor at Φ120. I use it in a bathroom that doesn't have a small window.

Looks very good. Time will tell, of course! Compared to the previous one I had, which was also considerably more expensive, this one is definitely better! Both in terms of noise and ventilation!

I expected better suction, it is quite quiet compared to others in its category. However, for its price, I recommend it!

Very good quality and price ratio. Completely silent and very efficient. I installed it in a bathroom of about 6 square meters without a window and it cleans the air very quickly.
