Product review (1 stars): Mesh is not fine enough to work. Don't buy.
I have been using these for about 10 months and now my lines are all clogged. More plumber costs for unclogging drains, again! The wire mesh is not fine enough to catch lint from the laundry. When I went to change it there was only a candy wrapper in there. It caught no lint at all.

 I'm throwing these all out and going back to Home Depot where I found a brand that does it's job.
