OK
I bought these to clean my bathroom tub and after using them now for a while.  I've noticed that 2 of them are beginning to break.  I guess that's why they come in a pack of 9 cuz you will expect short expectancy.  They clean scrub pretty well and I would definitely buy more once all of mines are worn out or broken.  Saves me allot of time from using all that elbow grease by hand.
