DO NOT WORK!!
I have a top load washer.  There is cat hair and some people hair all over my clothes.  ZERO hairs collected.  I tried a few different times, with one or more of these in the load.  I can't understand how they can sell these.  I waited too long to return them (over 6 months.)  I will be donating to my Value Village.  This is a huge waste of plastic.
