This was just what I needed for my spare room. I added a vent in the side wall and it was perfect.

Good product. Easy installation.However, I purchased qty. (2) and paid for overnight freight, as my AC guy was installing my dual duty exhaust fan system for our remodel. Received one the next morning and the second one came late afternoon after my AC guy was done. Had to run out to find one for him that looks different than what we received.

Basic ceiling vent. Though plastic, it does exactly was it is suppose to. Only issue (and really minimal one) is that there is only one stop screw on the top to keep the center from coming off. I added a second nut which resolved the potential issue. That would not keep me from recommending this or purchasing another if needed.

This was easy to install, had all the brackets and install parts needed and the color matched the ceiling paint.

Used this in a wall mounted A/C in my boat, works good to diffuse the air throughout the cabin.
