Review: Good product. Spring was fine. - The piece is sturdy, came quick and should work great for my purpose. Some reviews said the spring was too strong, but this hasn’t been the case for me. I do have a pretty strong fan behind it but it is also down the line from the fan about 2 to 3 feet and opened easily.
Review: I think it's a good deal. Better quality product than others I've used - I think it's a good deal. Better quality product than others I've used. Material feels stronger/ heavier and damper opens easily but closes tightly forming a better seal. Bought it specifically because you can install vertically or horizontally. Product came in on schedule.
