## Customer Reviews

### ⭐⭐⭐⭐⭐ seems just fine!
*by B***T on September 11, 2022*

I bought this as an "Open box" "Damaged"It was all there, and works just like it is supposed to.Had a couple dings in the frame, and the original packaging is "Just" a carton. no foam or padding, other than some little plastic corner protectors. (no wonder they get beat up so bad) Needed to add a plug to the wiring. (it comes with just wires on the end of the power cable.) I just spliced a computer power supply cord to it. The Variable speed controller works, but I really don't have any use for it. You would plug the fan into it, just like you would plug it into the wall. (after you put a plug on your power cable) I am just going to plug it in, when the exhaust fan is desired. The controller would be just something else to break, and I will have it on full blast all of the time, when I use it anyway.The gravity driven shutters are NOT air tight, but close enough for my pole building shop. This is just a sheet metal box, with a fan inside. there are not any mounting flanges or brackets. I plan on just bending 4 - 3.5 inch 90 degree angles, and pop rivet them to the edges, for mounting flanges. It will be on a make shift shelf on the inside of the building. It is a little noisy, but not overly so. "It's a high RPM fan, they make some noise...
