The device is remarkably easy to use, allowing for the setting of high and low temperature points.

The VIVOSUN fan not only came at a more attractive price point but also outperformed my old unit in every aspect. Its effectiveness in temperature control within my home has been exceptional, offering a hassle-free solution to maintaining an ideal climate. In summary, if you're in the market for a register booster fan that promises and delivers efficiency, ease of use, and reliability, the VIVOSUN Quiet Register Booster Fan is an outstanding choice. It represents a significant upgrade over other options in the market, not just in terms of cost but more importantly, in its performance and quality.

Bunch of whiners on this review board. Works well my daughter’s room was super cold and this thing works well. I use level 8 on it level 10 is a bit noisy. It now has been running straight for 3 weeks now and no issues. The cord is kinda annoying wish there was possibly a battery option.

The device is of good quality and works as expected according to the user manual (strongly suggest everyone to get familiar before using). The primary purpose was to improve air flow into a room during both heating and cooling seasons. Unfortunately, I cannot detect any perceptible or statistical effect of using the device: the room temperature was continuously recorded from a digital thermometer but it did not show any difference compared to not using the device.

Didn't expect that it would help a lot in our house (sidesplit) as main bedroom is at the opposite end of the house from furnace..always hot in summer and cold in winter..found room much cooler after installing unit.. I run at maximum fan speed which is less noisy than our standup fan which we are use to..lower settings are very quiet. I set at 65 so it comes on just after air kicks in.. so far very satisfied..bought two for my daughters house.

This register works amazing Keeps the room nice and warm compared to before
