Cat loves the whole setup, but the product itself was...cheap. Scratching post is already coming unglued, one board broke after our 11lb cat jumped up on it, the screws we received were too small for the drywall anchors, and there were no predrilled holes for the brackets. The instructions said not to use power tools, which meant installing one bracket took about 5 minutes. Now that its up its pretty good, but we had to buy our own hardware to install it. Cool idea, but would probably be better to just build one yourself.
Update: yet more of the tree has fallen apart. Our cat sat on the board and it collapsed. I can't believe it's legal for stores to sell products that are so poorly made. Buyer beware, your kitties could be injured! :(
