I purchased three of these about 5 years ago, and I love them. They clean up well, even with pets. My older dog went through a period where he used it as his bathroom, but it cleans up well with an enzyme cleaner. One reviewer mentioned issues using it over crushed rock, which wouldn't clean up as thoroughly due to leaching into the soil. Personally, I feel they wear and clean up well. They look as good as the day I purchased them and are in a heavy traffic area. I plan to purchase another one for a different area soon!
