I got it for my kitten to keep him entertained when I'm out of the house, among other toys.
Pros: Sturdy and elegant, fits very comfortably even in an apartment. The quality of the materials seems good for its price and it doesn't wobble. Of course, the kitten is only 2.5 months old, it will show how much it can withstand when it grows bigger and heavier.
Cons: There were no assembly instructions, only pictures. I wouldn't recommend it for large cats, only for small female cats or kittens.
