VEVOR 10 inch Exhaust Fan, Wall Mounted Attic Fan with Variable Speed, Temperature & Humidity Controller, 1000 CFM, Automatic Shutter

High quality manufactured item. Was very well packed for shipping. Set up was easy, but you MUST read the manual before trying to set it up, then read it again. Once installed it is extremely quiet...mine is installed in the attic window and I can't hear it running at ground level. There are a ton of options that make it very versatile when it come to speed, temperature and humidity settings.

Very straight forward and easy to install. Works great for our hydroponics garden. Adjust for temp and humidity. Programing is easy if directions are followed carefully.

the fan itself is very nice. Louvres work smoothly, and fan has good power. Was easy to mount. Took away a star because the control panel is very difficult to use. Instructions in the manual are crappy and unclear. The digital face is impossible to see when it's daylight (very bad for a greenhouse). We have resorted to just manually turning it off and on. Tried finding some you tube videos on setting it but unsuccessful so far.

Purchase this fan to help with airflow in my 8 x 16 greenhouse. It did exactly what I wanted. Keeps the interior much cooler in the summer sun. I was hitting 128 degrees in there and now it stays pretty much a few degrees above ambient temps once it's on. Have it set to go on above 90 degrees. It's powered by a small solar battery and panels I have set up nearby. Only pulls 45-ish watts on medium speed.

We were in urgent need of this fan and the controller did not work. The fan does work without the controller, but at a consistent high rate of speed. Because of the weather conditions we cannot do without the fan at this point.

Plan to update with a setup because the instructions are actually kind of iffy but this is a really nice exhaust fan for the price. I put one in each of my rental house basements and now plan to find one to replace my own broken attic fan. So far I've bought a few vevor items and I'm very surprised at the good quality.

Easy to install, looks professional. The exhaust fan moves a lot of air. Instruction for operation are not very informative.

Eh mixed feelings. I love the fan, but the controller wants to switch on with high humidity. I only want it to switch on and off by temperature, but when in auto it also looks at the humidity which you cant turn off or set a crazy number. So in a rain storm, this attic fan keeps turning on if left in auto for the winter. That aspect kind of sucks, but other than that it seems to work good. Its not the quietest Ive seen, but also not too noisy. It fit good and was easy to hook up. Ive only been using it for a few months.
