Cats love it, which is great, but it's very wobbly even when tightened to the ceiling and is slightly bent forwards. We're going to fix it to the wall to try and stabilize it a bit. The instructions were extremely misleading but once we got started it didn't take long to build it - the holes for the ladders that connect to the little houses were in the wrong place too, so the ladders sit at a weird angle but it's not a big deal. Overall is a great cat tree for the price, and definitely worth it.
