I didn't feel bad about spending $25 USD on it after receiving it. I did add a little weather stripping to each half inside up against the little ridge that stops the door from turning closed further, just to seal it a bit more, but it looks to be a 90%+ seal without doing that, at the least. Depends on your use case whether or not you will want to beef it up further. ### ⭐⭐⭐⭐⭐ Impressed...very well done! *by J***L on November 17, 2024* Put on an air duct in our 5th wheel so we can control the heat going into the tank compartments. Perfect for that fix! ### ⭐⭐ Low quality *by M***O on April 15, 2025* Low quality, arrives dirty, and unlike in the misleading photos there is no actual gasket on this damper. Just plastic to plastic contact. The knob is also extremely loose unless you tighten it with the screw under the lever but it still works bad and isn't very secure. I have yet to check fit on my dryer ducting but I am hoping for the best given the other comments.
