Product review (4 stars): Works, but construction is cheap.
It works, but is built cheap, VERY cheap. It seems very flimsy, but it actually does seem to work at keeping the lint down. Our dryer vents into our carport (yeah, you read that right), and due to the logistics of the laundry room and carport, moving the dryer to another wall would be a major hassle and the lint that accumulates in the carport is very annoying, we also tried routing the dryer line different only having the effect of creating excessive back pressure on the exhaust greatly reducing drying efficiency, so this seemed like an easy and sensible solution. It actually seems to work, and it doesn't seem to create back pressure on the dryer exhaust line and reduce efficiency.
