Good Quality... Springs are very light though
Very Well Built Unit.Using this in a kitchen island hood vent... the wind caused the flappers to slap open/closed (annoying).So I put a heavier spring on the shaft...PROBLEM SOLVED!

This work great.
I purchased this to prevent air from flowing back in through the extraction vent on a varnishing both I build. It worked just fine. The vent tubing fit easily on it.

Flimsy
First one came and it was broken. Returned for a new one and although it's not broken its really not very well put together. The foam was misplaced so I had to remove it and reapply it so a seal could be made. Not happy with it, but I'm gonna install it and see if it does the job

Tried two, both duds
First came and damper flaps were all bent up. Replaced with another and it was worse- flaps wouldn't spring closed. All bound up. Will return it also and try a different brand.
