MOTCTQVD Smart Register Booster Fan Fits 4” x 10”, 10-Speed Quiet AC Vent Fan with Thermostat Control for Heating Cooling

Bought this for my son’s room and it has been great. Very easy to use and it’s more effective than I was expecting. My son’s room has a huge window so it’s hot in the summer and cold in the winter, this vent fan is great. Fit my vent hole perfectly and looks better than the original vent cover. It’s not loud, like any other fan.

Cold, powerful, and tons of options. The setup was straight forward, a simple removal of the OEM unit and an easy replacement, even using the same screws. The cord was a bit of headache, routing it to the nearest outlet looking everything but discreet.. but I understand it’s pretty unavoidable, especially with the in-line external thermometer. The included remote is handy, and offers a plethora of options—all nicely detailed in the manual. The automatic fans are reliable so far and definitely make the air cooler, and at the least blown faster. The display is bright and clean.

I’m really impressed with this register booster vent fan. I was skeptical but thought I would give it a try in one of my bedrooms with just one vent which doesn’t have much airflow. Easy to set up and fits perfectly in any 4x10 inch vent. Once you set it up it works great and it definitely improves the airflow, in the room. And surprisingly it seems to make a difference. It includes a full function remote and the unit seems to be very well made. I believe it’s worth the money I spent on this. Highly recommended.

We purchased 3 of these vents less than three months ago and two of them have already stopped working. After troubleshooting it seems to be an internal issue with the electrical system. Unfortunately we’re just outside of the return policy so I guess we’re stuck with the damaged units. I was hoping to keep our girls rooms a little warmer through the winter months, but oh well. I do not recommend wasting your money on these.

Seems like it’s built to last. Fit my vent well and was easy to install. I use the fixed fan speed and that has kept the room temperature more comfortable than it was before. The battery for the remote doesn’t seem to work otherwise it would be 5 stars. Adjusting the settings manually on the face plate is easy enough.

I absolutely love this fan!!! We put it in a vent that’s a little outta place to help cool the area! The fan is quieter than most, even on the highest setting! There is a noticeable difference in temperature within about ten minutes!!!! My ONLY “problem” is, the remote doesn’t seem to work from sitting about 10 feet away. I assume this is because the remote sensor is at floor/vent level. I realize that having an elevated sensor isn’t really feasible, so I understand. If my vents were in the wall/baseboards, this would be amazing!!! If you make one for a 4”x14” return, let me know! I need two of them :)

Seemed to work okay but it was wired backwards or something.

I have an upstairs bedroom that is always hot in the summer, despite the rest of the house being comfortable with the central A/C running. I was skeptical that this product could make a difference... but IT DOES! It was easy to install the booster in the duct vent. I leave the booster running at high speed during the day with the bedroom door closed, and the room stays comfortably cool. I used to dread sleeping in that hot bedroom, but even in these 90+ degree days, it is now a cool pleasure. I can leave the booster running at low speed (level 2) while I sleep - as it is virtually silent at that level but still provides some gentle airflow. It really was a great purchase for me!
