I got this at a really good price, it was easy to assemble, and the cat was trying to climb it before I even finished. The only complicated part was the final pole up to the ceiling - you cant do this in the upright position. I also had to saw a bit off this pole because of the height of my ceiling, and the tension this was causing in the spring (where the pole inserts, allowing some flexibility). My bigger cat hasnt been on it yet, which will be the test of how strong it is, but it feels like it should stay in place even with a forceful jump.
