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.

Booster fans are amazing for fixing those problem rooms that always seem too hot or too cold compared to the rest of the house. These are nice looking and fairly quiet. I've never used the remote. I just set it and forget it. The only time I need to adjust these is when I switch from AC to heat with the changing of the seasons. When my furnace kicks on, the booster fan kicks on and increases the flow of the heat into the room, and vice versa. Great product.

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’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.

the boosted heat/AC is a good quality for what you pay for

I wanted to review this after the first night, but made myself wait a few weeks to evaluate it more than one night. Our bedroom feels like it gets extra hot at night time and I'm someone who cannot sleep when the temp is above 70 degrees. We only have one free vent in the bedroom thanks to the amount of dressers my wife has so I got this hoping it would make a difference so we wouldn't have to put a window unit in our only free bedroom window. All I can say is I wish I would have bought this years ago. I am so impressed with how well it does! It has multiple settings where you can keep the blower on a set setting or you can set it up so that it adjusts based on the temperature difference between the vent setting and the room, and you can adjust it specifically for heating or cooling. I keep ours set on the max speed blower all the time and it keeps the bedroom a little too cool during the day (which is fine since we're not really in there) and keeps it much cooler at night. We're in the middle of 95-100 degree weather right now and it is still performing beautifully at keeping the room cool during both day and night. The only thing I do not like is that I find the settings to be a little difficult to set up or understand at first- but once you get it, it's fine. Definitely still worth it for how well it works. If you have a hot bedroom, I definitely recommend giving this a try!
