The delivery is very weak: the seller has chosen a business that does not really book the packages, they just leave a calling card in the mailbox without bothering to knock at the door. Scratching boards and have solid air. Unfortunately the threads of the screws is too short and I can not climb the tree correctly (I have 2 separated parts, which makes it completely unstable). The seller offered me to go buy a screw myself: the problem is that I have to take the time to take the dimensions, to pick her ... I should have moved me directly to go buy a cat tree, it would be returned to the same.
Conclusion: quite good quality (even if manufacturing defect), but binding service.
