Rated 5 out of 5 by 2 reviewers.
Rated 5 out of 5 by attractive appearance We had difficulty locating the air conditioner vents we see in business ceilings. No stores have them on display. We cut an opening in the ceiling tile to hold another type of vent cover but it was ugly and eventually cracked the tile. My husband attempted to cut another opening in tile and only succeeded in ruining more of the expensive lay-in tiles. Who decided to call these defusers and not offer them on display at any of the stores selling drop ceilings? It was so easy to install and required only the proper duct tape (not the silver stuff). It took about 10 minutes for my 84 year old husband to do the job. July 3, 2012
Rated 5 out of 5 by Put together well. Hey, it's a vent. For what it does, I would like to see it a little cheaper. June 11, 2013
