Purchased two in hopes of improving cold air flow to the kitchen and to a bedroom. Tested the fan before installing and was not impressed with the volume of air. Decided to install anyhow just in case. Installed in an 8" duct as per the instructions. I was not able to tell any difference in the airflow. Decided to remove and return.
In my opinion, this fan is totally ineffective. I wasted a hour installing and then having to patch up the hole I cut in the duct when I removed it for return.

Rated 4.0 out of 5.0 by Tommy The sticker that states the direction of air flow was backwards. The product works well and was easy to install.
The product was what I expected but the direction of air flow sticker was backwards. Consumers not knowing this would be quite upset when they had to reinstall the product again.

I purchased this product because it said 6" - 8" and by the picture looks like it would adjust to my 7" flexible duct. For any flexible duct you have to buy adapters to install. I think that the description should have said mounts into 6" to 8" metal ducts. For flexible ducts, you will need to buy adapters. I waited for 5 business days to receive a product that can't be used. I could have bought an 8" fan and decreased the size by getting adapers.
