workd=s well and has simple to use controls. Keeps the room warm when it was constantly cool before.

This thing is great! We don’t use it in the traditional manner. We have a wood stove in our basement and registers cut in the floor upstairs to let the heat up. We got one to put in the register right above the stove and it works great. As it warms up downstairs it turns on and just pumps that heat up. So far it’s proven to be very durable and it’s not very loud at all. No different than a fan

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

Worked great for less than a week. Then it broke. I’m pretty handy, there is no way for me to fix this. I ordered a replacement. Hoping this was just a lemon. It’s not “quiet” you can absolutely hear it, I did have it on the highest setting though but you will hear it.

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.
