Je l'ai acheté récemment et installé il y a 3 jours maintenant et sa marche pas trop mal,je m'attendais a mieux mais sa va dépanner, il est très bruyant au-dessus de la vitesse 7,suspendue ou posé sur coussin,il est pas discret malheureusement, très déçu a ce niveau et l'interface est pas très pratique et opérationnel, il faut le régler au minimum pour que la turbine se lance en mode automatique car si ont veut tout paramétrer, sa le coince et il se déclenche pas malheureusement, alors que c'est fait pour mais bon,il fera le temps qu'il fera et repartirai sur du plus silencieux et précis, sans blocage automatique et affiché 1370m3/h mais je vois indiqué 800m3/h,est-ce normal et les chiffres sont trompeurs, car il me faut 1370m3/h et si il peut en tirer que 800m3/h,normal qu'il penne,tout le temps a fond alors que sa devrait pas,déçu pour sa qu'il fait du bruit car la ,il manque 600m3/h pfff Autrement il fait le boulot,rien a dire,livraison rapide, arrivée propre,merci

It looks like a good product, I have not used it yet. I wanted to use it to improve the air quality in our home due to dampness and previous smoke damage. I was not aware that I needed to buy a filter to use it inside as I do not wish to vent it to the outside this time of year.

A little to noisy, also when set to low RPM there is a little humming noise coming from the electronics. Airspeed is good, but unfortunately I wanted to use it in the livingrom and therefore it is to noisy.

Elektroniken, sannolikt hastighetskontrollen, låter och stör mer än ljudet från Fläkten. Oväntat surrande ljud. Kanske byter ut hastighetskontrollen själv.

le ventilateur est trop bruyant. Il doit être installé dans une pièce de repos.

The delivery time says 4 days but it arrived in 7. 4 days setback as i needed it to arrive in time. I had to pause the works in the basement because of it. Also the diameter should be 101,6 mm and it's 96 mm, so it does not fit the prepared ventilation tube. Another setback. Thus the 3 star score. The vent works nice, temp and humidity mesures correctly. Let's hope it will last.

Much noisier than I anticipated. Over all the build quality appears to be excellent, compared to a similar products of similar function, but I was disappointed as to the noise level with the fan.

The fan moves a lot of air. It is used to boost A/C to a section of my game room with a lot of windows that needed extra air. However, the control module does not work correctly. You can't set a high temp which makes the unit worthless. They have no phone number for customer service. I emailed them and explained the exact problem off the high temperature not being able to set. They want pictures and video before they do anything, and will get back to me in 48 hours. In 48 hours I will be at my other home in FL so they can't help me get it fixed. Again, great fan but no user friendly service support.
