Register Booster Fan Fits 4” x 10” Register Holes, Smart Control Heating Cooling AC Vent Fan, 10-Speed Quiet Register Vent Booster Fans with Thermostat Control & Remote Control

It really does help our upstairs bedroom cool down! Quiet to level 5 then you start to hear it but not annoyingly loud.

Great asset for hot rooms. Easy to use and set up. Very quiet and increase power helps cool the room nicely

The fans stopped spinning after four months. I try to avoid writing bad reviews but I reached out to the seller about the fans malfunction and didn’t get a response. I ended up buying a new one, different brand and different seller.

I love it and will by one more, only problem I am having is adjusting the temp with the Sensor on the Power Cord being to close to the vent itself!

Product arrived on time. Does what it says it does. Kind of cheap plastic feel but works. Fan does blow, from standing over top it pushes an extra 2-3ft of air. No remote controller included though as it mentioned on the site. Might give 4 star if remote was with it. My suggestion, if ya have the $ get the better one, if not this works just dont expect a 60$ Product.

I am updating my original review. I thought the fan quit working after about 2 months. I was wrong. After reaching out to customer service through Amazon, they explained the functionality and it is working as it should. Their prompt response and guidance alone warrants 5 stars. The fan certainly does help better balance the temperature in my split level. The upstairs rooms are not as cold in the winter and have been cooler so far this spring.

Awesome vent fans. Last season I only used the vent fans to cool one of our bedroom instead of running the supplemental window unit. Very quiet at medium to low speeds, can't tell it's even running. It's a good buy for the results.

Broke within a year. Screen started going bad and fan motors started making a lot of noise as the bearings failed. Couldn’t reach manufacturer for warranty.
