Not the most attractive thing on my ceiling, but it helps push the air down instead of up! Works very good if you have high ceilings.

Very easy to install and very unobtrusive. Most people never see them. Mine are on the ceiling so they will last a long time.

Great hold
No smell
Stays cleans
Doesnt start yellowing
Diverts very well

I am happy with these but I would be more satisfied if they were larger width wise and diverted more air away. They stay stuck to wall vent and do a good job.

These deflectors work great. We have heavy thermal drapes that go all the way to the floor, and we used to have to carefully arrange them to tuck the drapes behind the vents so the warm air from the floor registers didn't just blow up between the drapes and the windows. With these covers, the air blows out into the room. The plastic is heavier than I thought it would be -- good for durability. Width easily adjusted to fit our vents. I highly recommend this vent with neodymium magnets over the vents that use old ceramic magnets. The neodymium magnets are tiny, and therefore less visible, and they provide a super strong hold. The clear plastic vent is nearly invisible in place. The covers came with a roll of clear nanotape. I'm not sure whether it was intended for use with the deflectors, or just a bonus product. In any case, I used a couple of tiny pieces of the nanotape to firmly fix the two halves of the diverters together once I'd adjusted them to the correct widths for our vents. Nanotape is great stuff. Bottom line: I've bought cheaper air deflectors in the past that were flimsier or didn't stay together. These diverters were a bit more expensive but they look good and feel like they're made to last.
