It is very good for its price, provided that it is installed correctly.

DO NOT use it with a 100mm pipe and DO NOT attach a flexible extraction hose, as it will vibrate and make noise due to its power.

The extractor comes with a 150mm outlet, and a reducer to 125mm is included in the package. In my installation, I used the reducer to 125mm, and the extraction is done with PVC, taking a route of about 4.5 meters until it exits (including two turns with four open bends). I have installed four supports with rubber, hoping to reduce the noise at least a little. In my installation, there is some noise, but it performs very satisfactorily.

The extractor has two speeds, low and "crazy"! 95% of the time, you will use it on the low speed and you won't have any problems even if there are 2-3 pots boiling or if someone wants to smoke a cigarette without having to go outside in the cold. I only recommend using the high speed for emergencies (like breaking a jar of vinegar and entering the kitchen crying) or if you have an open space and want to freshen up the entire area, but you will have to tolerate the noise for 10 minutes.

The construction is good/satisfactory, but keep in mind that you will not find such power for this price anywhere else, even in much more expensive and well-known brands.
