I really don't have anything negative to say about this product.  My cat loves to play on it, stretch/scratch on it, and sleep on it.  I really like the following things about it - it's tall but not too wide so if you don't have much room it's great, all the posts are wrapped in sisal for scratching purposes, lots of levels, it has a covered house, easy to put together, it's a very neutral color so it fits in easily, VERY reasonably priced, and the faux fleece is also a nice touch.  If you're on the edge about it, go for it, you'll love it!
