my cats are obsessed with this tree so I'm pretty happy I bought it. There's just a couple things I'd change-the top is held in by tension, but I have short ceilings so i had to saw of the tube they provided in order to fit it. They don't tell you that could be a posibity in the directions. Also the undersides of the perches are the unfinished particle board. since the tower is tall, i had to paint the underside of the top one because it was ugly to look at from underneath. i also had to buy new hardware, because what they give you is awkwardly small if it's not pressed right up into a wall. and i had to buy some hardware to hold in the top as it slid around when my cats were playing. with better and more varied hardware and if they carpeted the underside of the perches it'd be 5 stars
