I got this on sale, so not too shabby. Its cute, nice materials, two levels stable. Its not all bad.
BUT its not a very safe or stable cat tower if you put it together as intended. I didnt add the top tier (seriously, unless your cat is 6lbs or less, this seems like a bad idea) and I instead used the extra poles to reinforce the middle tier, so at least that is stable. See photos. 
Id buy again at the sale price and my patience level....
