iLiving 12" Wall Mounted Shutter Exhaust Fan, Automatic Shutter, Temperature and Humidity Controls with Variable Speed, 960 CFM at 1600 RPM DC Motor

Seem off to a good start easy to install Nice and strong .

Es de buena calidad y es versátil

Works well, and is much quieter than a cheaper one I bought. Has a temperature sensor and can be put on a timer. The hardest part is cutting a square into a wall. However, it does fit in between two wall studs. I mounted mine on the outside siding by using an oscillating tool to cut the wall out with.

Easy install and very quiet. Moves a lot of air in my shed

I really didn't have any issues during the install process. Once you have your hole cut to the correct size, the rest is just electrical. Then just plug it in and go. The thermostat controller works well and is easy to configure. The thermostat does blank after few seconds, but pressing any button brings it back. I guess it is for saving power, but not sure that is necessary since the fan unit uses 110 VAC. I am probably going to buy the larger unit for another building I have. One minor complaint is that the max. temperature setting is 99 degrees F. This should be fine for most applications, but worth noting. One surprising thing was the lack of including 8 mounting screws. I guess they were assuming that mounting the fan is unique for each user. Not an issue really, but you will need these screws to complete installation.
