Very poor quality
I bought the Mr. Clean Magic Erasers after using a generic grocery store brand.  I thought Mr. Clean would hold up better than the no name brand which lasted me three cleanings of my marble and grout shower.  Boy was I wrong.  After one use of wiping down the marble tiles and the bathtub, the Mr. Clean Magic Erasers literally started breaking apart.  Chunks of the sponge started to fall off and get stuck in my drain.  The quality of these pads are so poor, I will stick with the no name brand and spend a lot less.
