so far it was easy installation and the wiring needs a receptacle to plug in and I just used a extension cord. it is very quiet and my shed went from 101 to 97 pretty quick. I bought a 12x12 louvre vent to draw air into my shed and I can feel the suction.

Installed it in my greenhouse. Works great. Very quiet.

I put this in my shed to keep my battery temps down a bit and was surprised to see a 10-15+*F drop just by circulating air through there. I do have some poor man insulation throughout the shed so I am sure that helps but the fan is doing the work and making the biggest difference. Way better than just the normal vents without a fan. On my solar battery it uses 20 watts and I have set to kick on only at 83F. Seems more sensitive than another temp control panel. Not sure which is more accurate. Note the auto on function beside to set the other auto functions way outside a reasonable limit so the fan isn’t triggered based on something else than what you set it for but it is useful if you wanted it to kick on for 4 different modes it will H/L temp H/L humidity. I only use high temp

Works as advertised. It’s kind funky when it’s to the set temperature of the temp goes up and down.

Seams to work just fine. Hope it last a long time.

Very nicely built. Works flawlessly. The variable speed fan is good to have. I'm using it as a crawlspace exhaust ventilation fan, it's keeping moisture from building up under the house. We've had a lot of rain and high temperatures and terrible humidity this year. As can be seen from the photos I have it mounted in a wooden box frame. Fits the crawlspace opening easily and can be removed in winter and stored. Dried out the crawlspace very nicely better than it's been in years. I have it on a digital timer that runs for a few hours everyday. I disable the timer with a remote switch on rainy stormy days.

I am using it as a paint booth extraction fan it works great the only thing that I have noticed is that maybe the blades are not balanced it vibrates and is loud but it does the work that I wanted it for see pictures I even make me a shroud made of card board and I put some filters on it and like I said it works great

Works great upgraded the size by 2inches from the one that blew and my lord what a difference much more air flow in my paint booth

I like it, as described

I bought this for my attic and it runs but I cannot program the unit to shut off in the Auto Mode. I've tried several time to program it but it will not shut off.
