Kiroto 12 Inch Shutter Exhaust Fan, 1600 CFM High-Speed Vent Fan with Temperature and Timer Control, Wall-mounted Window Attic fan, Gable Fan with APP WIFI Remote Control, 12" Garage Exhaust Fan

I use it in my greenhouse and it keeps the temperature right where I want it.Set the high limit either on the manual touchpad or through the app, it kicks on and moves alot of air.

I bought this to cool our large attic which stays very hot during daytime. The part of the attic that it can be installed is almost blocked from the rest of the attic space, so the fan can only cool a fairly small portion of the attic. But its doing a good job. During super hot days of summer months in our area, thanks to the fan, we don't need to use the a/c until well into afternoon hours. It comes with an app and you can turn it on and off easily without climbing into the attic! 4 stars because we can hear it in the bathroom which is directly below the attic. But the noise is much less noticeable in the bedrooms. Sometimes I turn it off at night. Overall, we are happy with this fan and think it has made a difference in controlling the temperature and reducing our gas/electric bill

Does what I needed to do!Ventilation for the chicken coop. Keeps the temperature down!

Easy install. Good air flow. It's a fan.

Love how easy this fan was to install in our window and set up on the app! Also quite reliable in its programming. Turns on when it reaches the programmed tempurature. Very sturdy. Highly recommend!

Good Fan.Works as advertised.App is ok.You could pair a regular plug in fan to a smart plug, but then you don't have the more detailed control of the fan itself.

Works great, I can remotely turn it on and off, or use the temp settings to control it kicking off and on.I will say this fan is designed for a medium to large building. I do resin printing and wanted something to draw the "Fumes" out, but my builing is a 8x12 and isn't big enoughf or this fan so it was overkill lol. The fan slows down when I shut the door because it's too small. So this is intended for a bigger building, but it does a great job of sucking the fumes, and installs easy. I also noticed it has a pretty good seal around the vent flaps when they shut. I run a AC unit in my building and it didn't affect the ability to cool it in 98 degree weather.

Love the looks and how it works exactly has described.
