I have not used a rating system as it is not the color advertised. I would call it false advertising. This is the reddish pink color you will receive, not the gray stone in the picture. Not what I wanted, not what I ordered. If I had wanted a red pink color I would not have ordered it. Besides the color issue, let's take a look at it. It was sticky on arrival, not sure if it was some kind of coating or something. It's porous, so a thorough cleaning can cause problems if not done properly. The holes also provide my cleaning crew (woodlouse and springtails) with a place to hide and it's almost impossible to get them out without killing them, which is costing me money. I ended up using super glue to seal the holes, which is unsightly. I would not buy this product again due to color error and pore issues.
