I like the fact that it has 3 sides so I can rotate them. My only issue (an not just with this scratching board) is that little pieces of the cardboard come off and and on the floor after the cats  have used it for awhile. I will be glad to vacuum since they confine themselves to scratching on this and not on my furniture.

Pros: 3 sides, makes it useful for a long time.
Cons: cardboard pieces come off after awhile...not a BIG con
