Product review (5 stars): Great product - Needed a quick fix
Overall, it appears to be a great product. As I just received and installed it today, I do not have extensive experience with the unit. That said, the unit is very sturdy and well made. I had one quality control issue with the unit. After installing it, I did a test run. I put my hand in the dryer and still felt a breeze coming from outside. I went back outside and found that the plastic cap (that is, the piece that opens and closes the vent) did not close completely. On inspection, I found that the plastic cap had some rough protruding edges that stuck to the main unit when the cap attempted to close. I removed the cap from the unit and then used a razor knife to slice off the rough edges. I inserted the cap back into the unit and it then moved freely. It appears to be working fine now. I no longer feel any breeze when the dryer is off.
