For this size register, it would have been better to have a bigger fan volume of air. Still, it does help some so it is worthwhile. To add any increase to the air flow, you need to run the fans at 8 to 10. At that level, they are not quiet, but are still acceptable as long as you are not intolerant to noise while sleeping. The product seems to be well build and solid. Quality seems good. Price seems about right, neither low or high.

I like the fact that it has a thermostat that shuts it off so it's not running all the time. Fit nicely into existing vent and works great. I wish the fan was more powerful, but that would also mean louder.

I've had two of these for several years in another house. Just bought a third and am using all three in a new home. They pull the hot or cool air that gets left in the ducts when your system shuts off. So much more comfortable and efficient. This new build house is way more efficient than the last and yet these are still useful. Easy to install and set up. I think they are brilliant!
