Wertige Verarbeitung, geringer Lärmpegel, da gut einstellbar

Bluetooth doesn't work 😕

I've only been testing this fan/filter for a few weeks, but so far I'm very happy. It moves a ton of air in my 4x4 and the fan (which I installed inside the tent) is decently quiet when cranked up to max settings.It was very easy to assemble and install, and I have no experience with these kinds of things. I did opt to seal the ducting with aluminum foil tape in addition to the hose clamps -- the tape needs to be bought separately. That said, I don't know if that's even necessary.The smart monitor is REALLY nifty. Tons of settings to automatically adjust for different scenarios when certain conditions are met. When I thought I had a problem with the monitor (it was actually just me being dumb though) customer support responded to my question in a few hours. Really can't complain!I'll try to update a year or so down the road and let you know how well it ages. In the meantime though, I'm a happy camper..

Perfect fan for the application. Not the Bluetooth version that is controlled with the app. Perfect controller though to set heat and humidity ranges as well as fan speed.

Wirklich perfekt für alle Anfänger und Interessenten. Leicht aufzubauen, zu bedienen und hält bereits sei 10Monaten geruchsfrei.
