They do exactly what they 're supposed to do they float in the wash collecting lint and hair so it doesn't stick to your clothes or clog up the drain. I didn't think these would work, I was sure I had wasted my money , but they work perfectly! Clothes come out of the washer with significantly less lint which helps a lot when line-drying clothes. Definitely recommend!
The picture shows 2/3 of the lint captured in a mini washer by Della. I washed 2 cotton shirts and one pant made from a blend. The machine has a lint catcher as well. My black shirt looks better than when it comes out of a bigger fancier machine! This caught the majority of the fibers (and possibly some cat hair) that where in the water during the wash. Good investment, glad I purchased.
My washed clothes used to be covered with lint, hair, cat fur, etc. These laundry hair removers are sturdy, and work well to capture the annoying fuzz. I use a top loading, standard washer, no fancy settings. You can see in the photo how much one of these gadgets can collect. I used two and the results were great.
