Register Booster Fan, Fits 4” x 10” 140CFM with Remote Control, Smart Vent Fan Booster with Adjustable 10-Speed Control, Quiet Heating Cooling with Thermostat Control for Wall, Floor

Works well. Pricey. Easy to install if you have the right size duct.

We have an older home and do not have the money to redo duct work when two of our rooms are not getting proper air flow. We bought these as a solution, and they have been perfect. The instructions were easy to follow for setup. You can change the power level, fan noise, cooling, and heating.

Works great as it should. Yes it can be a bit noisy if you have the fans turned all the way up but what do you expect when there's fans and a motor. It definitely pulls more air into the room making it cooler in the summer. I will definitely buy more if other rooms need these.

nice for the guest bedroom because it is always chilly or hot.

This vent helped to significantly cool the upstairs of our older home. With one in each of the bedrooms during a very hot summer, the air was cooler and much more accommodating!

Fan worked but it had multiple screws missing under the grate. There was only one present.

We have weak air flow to some of the upstairs bedrooms and this device helps boost the air flow. One thing to consider when ordering g these is the size register they are going to be fit into. Most of ours are to big for this size booster.

Easy to pop in & get circulation of air flow of cooler air. Great price. Quite no noise.

Works great. Pushes cold air up to the second floor adequately
