Works great to keep the chicken coop cool during the summer. Moves air really well through the coop. Very easy to install.

First Vevor purchase. I was pleasantly surprised by the quality. The fan is strong and the controller allows you to dial the fan for what you need. I installed this fan in our chicken coop. It’s nice being able to set the temperature or humidity level on the controller. Much better than just having on/off or timer only. Will be looking into other Vevor products based on this purchase.

Funciona despacio en las opciones no explican como aumentar las velocidades pero hace el trabajo trabaja todo el dia a baja velocidad solo descaza enla tardey noche

Great fans! Work just as they're supposed to. Purchased a 2nd one after we saw how well it helps with the dust in our barn

Works perfectly!

Works awesome. Would give it 5 stars, but it does cause interference on my security camera when running. Not awful, but does make the camera image a little wavy when operating.

It took a while to get to reviewing this because I mismeasured the window I wanted to put it in, only to find it didn't quite fit when it arrived (entirely my fault). Now I have a panel built to fit it into a larger space and it works very well. It comes with everything you need to attach it to a wall, either on the inside or the outside. What I did was build a wood panel to fit it into a window frame and screwed it to the window frame with my own screws, and it's working very well for me. The trickiest part of my installation was building a panel that fit the space, with a hole in the middle that snugly fit the fan. If you fit the fan and plug it in then it will spin and do all the things you'd expect a fan to do. It also comes with a controller that measures temperature and humidity, so you can configure it to activate based on temperature going too high or too low or humidity going too high or too low. You can combine the options, so it activates if it gets too warm or if it gets too cold or if the humidity goes outside the range you determine. Or you can tell it to be \"on\" or \"off\", which are pretty self-explanatory. The controller can control two fans, although it's hard to see that being hugely helpful unless one of the fans has a long lead to extend the distance between the fan and the controller. If you have a space big enough to put two fans in it, and putting them more or less side by side makes sense, you can control them both. I guess you might use that if you're working with the biggest fan option and still need something more powerful. The fan will adjust its speed based on how far out of the acceptable zone the air has become. When I first set it up the reported humidity was 67% and I set the target to be 60%. It ran at maximum speed for a time and then, as the humidity dropped, it gradually slowed down until it hit the target humidity and turned itself off. Then the humidity slowly started to rise and it gradually increased its speed to correct i

Works as advertised but the display is not bright enough to use during the day in a greenhouse. With the sun shining in, you need to put somewhere deeply shaded.

Put this in my boathouse. Works great. Moves the air as indicated.

I'm using the fan to exhaust cool air from by house into my attached garage to cool it in the summer. The temperature controller works quit well and has several modes. What I really like is that I control the power to the unit with a smart switch which allows for a timed function plus I can use Alexa to also turn it on and off. Even when cycling the power to the control unit, it comes back on where it was set previously.
