Product review (2 stars): Hardly stops lint
Not sure what everyone is saying or maybe I'm doing something wrong?  This thing lets through more lint than it stops, I update this later in the week with a picture.

Slipped over washer hose then secured on, ran wash machine and was shocked to see that more lint passed through than was stopped.  I originally had one of metal traps on there that didn't work so figured for this price I'd give a try.

I don't know if my expectations are too high because as said this does trap some lint but I figured more than 25%.  Now I have this installed inside the compatible metal mesh trap and even running two doesn't really work.  My drain is pumped from sink to line so I need to eliminate all lint so that my pump lasts, this is not the answer.
