I bought this because it was touted to be one of the better sponges out there and I was looking for something to easily take out the tough stains in my kitchen sink. This gets the job done BUT the reason I gave it four stars is because I was expecting it to be like the magic eraser and work wonders but it's not on that level. I like that it can be washed in the dishwasher, re-usable, does not scratch easily and is double sided. Overall it's a solid sponge but not the miracle worker I was hoping for.
