Fast and almost silent ❤
It does its job, obviously full speed it sounds like a turbo slightly but if you run it a few notices under full power then it's almost silent, I would reccomend this to anyone! Perfect buy, easy to install and away you go!

Amazing!
Brought it to attach to my Glowforge exhaust ducting. It is such an improvement on the noise level previously. I’ve mounted it on the wall, and that was easy enough to manage too.Would recommend it to anyone wanting something for a similar reason.

Quality fan
Not as quiet as made out to be 35db at half power but is quieter then cheaper fans but the overall design and finish is miles better than my old fan

Quite fan
Extremely quiet on the lower setting. A bit more expensive than normal inline fans, but if you want piece and quiet it could be worth the investment
