Review: Works as expected but the effect is not measurable - 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.
Review: It works - Bought this to boost airflow in bedroom. It’s farthest room from air handler. It works good. It comes on and off based on temperatures you set. Kinda wish it would just come on when air flow is sensed.

### ⭐⭐⭐⭐ Warm room finally
*by B***N on 25 January 2024*

We moved into a new house last year and we love it but some of the rooms are a little chilly in the winter. I bought this fan to try to warm the master bedroom. It works very well. Our master bedroom is the furthest from the furnace and I don't think our system is balanced very well so the fan gives that extra boost to get warm air to the bedroom. Exactly what we needed. It is a bit loud but I don't mind. We sleep with a fan running anyway and this is no louder than that.
