Abida 4" x 10" Register Booster Fan

Works well. Wish I could buy another

Air flow is great! I put this upstairs due to it being warmer in the summer. It keeps it very comfortable up there. The noise level is no different than a fan. Great value for the money spent. Fits perfectly where the old vent was. The functions are easy! Love that it has a remote!

A very handy helper to add air flow to the rooms that are hard to heat and cool. Very quiet does a good job. Wish I could have found one in the 3" x 15". modified a duct to make it work.

We have a spare bedroom turned nursery that never seemed to cool off in the summer or heat up in the winter. As a last ditch effort before looking more seriously into updating the whole system, we tried this fan and wow! The room is much cooler now that it is summer time and by tracking the temperature with a smart thermostat, I can see that it stays constantly around the same temp where it wouldn’t before. I’ll be honest, I didn’t read the manual enough to figure out the auto start of the fan, so I just leave it constantly running, which is fine because the baby enjoys the added white noise.

If you want this to actually be 10% useful the amount of noise it makes is unbearable. It almost reminds me of a card inside of a bicycle spoke…. It’s pretty bad. It fits well, it moves air but at the cost of your sanity. Also the remote I got rattled on the inside like parts were broken
