Washing Machine Hair Catcher, Reusable Floating Mesh Lint Filter for Pet Hair and Debris, Laundry Drain Filter for Washer, Prevents Clogging, 3Pcs (Pink)

These are plastic thingies that supposedly catch lint. I used three of them because I have a lot of dog hair and cat hair on certain items that I wash. They caught about 1/8 of an inch of something in the bottom of each one and then didn't catch any more. I cleaned them out and put them back in and the same thing happened. They just don't work.
