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.

I ordered this to go in the 2 upstairs rooms since it stays either to hot or to cold. I was able to install them just fine and got them set to the temperature wanted but the unit doesn't kick on when it's needed. I have it set to 70, the room says it's 80 and the vent says it's 75 but it's still not coming on to cool down the room. I don't care about the vent temp, what matters it's the room temp. It should kick on when the room is above the set temp. I'm gonna have to return it due to that fact. I don't want my kids suffering up there due to the lack of ac making it's way up there. That's why I bought this unit but it's just not cutting it.
