Product review (4 stars): Easy to install
These fit tightly to the washing machine hose.  So far, I've only done one load of wash, but the lint trap stayed secure around the hose. I wasn't sure if the water pressure would cause it to slide off.  After the load was complete, there is a bit of lint in the trap, the holes seem a bit large, so i'm wondering how much still get thru, but I do know they are at least catching some of the lint and staying on the hose!
