The light covers that came were just what I needed to replace old broken covers. Easily popped into place.
The air was coming down so strong where I sit it even made the picture frame on the wall move. In summer I'm freezing, in winter I felt like I was under a hair dryer. Something had to be done. Found this and crossed my fingers. I'm just short of 5'1". I stood on the desk and was able to slip this in place in 15 seconds. Hallelujah! It diverts away from me and promotes air circulation where it is still comfortable.
Good product. Well packaged. Prompt delivery. Thanks.
