I've seen others posts that said these don't work, but you need to understand how they work. The pet hair doesn't stick to them, but pulls ocks the pet hair off of your laundry so that it can be collected in the lint trap/rinse water. I have two sets, one each for washer and dryer. I wash our pet bedding every week, and the amount of pet hair that is coming off of their bedding has increased dramatically since I've been using them. I'm really happy that I'm getting so much more pet hair off of our laundry (including our clothes from the dogs snuggling with us). We have two Brittany shedding monsters!
