The fan works perfectly. It does exactly what I expected it to do.

So far I am satisfied with purchase

This product did not really make any difference and may have blocked more airflow than it passed.

The Air Flow Register is easy to install although it did not quite fit my register area (too small). I had to buy masking tape to cover up the area that was still exposed. The fan works but it is noisy even at the lowest fan speed. Since the weather has not been hot for any length of time, it is difficult to evaluate whether there is a noticeable difference in the coolness of the room. Because there is an electrical wire leading from the fan into a socket it is not the kind of thing you would want in a highly visible area. It is a good temporary measure.

Helps equalize the temperture for that room. It is noisy than I thought it would be.

It seems to be helping with the air flow problem that I had with the second story of my house. This is a great product. I would recommend this to anyone.

Noisy, one of the dials won't stay on, doesn't pull air very well.

Dimensions of wall duct it would fit were not given.

needs to be quieter and have a longer cord for wall mounting

Quiet operation and boosted our airflow by about 50%. Excellent customer service and received the product quickly. Will definitely do business again with Smarthome.
