Pros: Very easy to put together, taller than I expected which is a good thing, I got it a a great price, my cat loves it!
Cons: it sheds like crazy (but it vacuums right up so not a huge deal), I wish the bottom were heavier or wider,  when my cat plays on it I'm afraid it will topple over(I weighted it down with a paver stone). 
Overall, Im Happy with it, it's meant to be played with and my cat definitely does that so if I got it at the same price that I got this one I would definitely repurchase.
