Crumbleing

First off I must say using the magic eraser actually works!!! Magic eraser can be used for several different reasons. I use it for the bath tub, shoe, counters, drawing on walls and even scratches on my car!!
Other than that very disappointed. Every time I use the product it crumbles in little pieces and creates a huge mess. The cost is already costly and does not last long at all. I can use it for 3 min and it is already falling apart.
Please make stronger material!!
