It's okay.
I have 7 dogs.  Needless to say, dog fur is plentiful.  I also have a brand new dryer.  So, I am not sure if it is the new dryer doing an excellent job, or that Hair Remover Ball.  When I used it, I didn't find a whole lot of dog fur to clean off of it,  BUT I did find that it flluffed the laundry up and didn't allow it to twist and tie itself up, so I am really glad about that.  Either way,  it is okay.  But the dogs look at me, drooling for me to throw it !  Sorry pups.
