My 3 Cats Love this Condo!! Easy to assemble, soft material, great quality, great price!! 
Lots of play area, but does not take up a lot of floor space. 
The only negative- the round circle does not stay hanging where it's suppose to be. The screw is not right, the circle falls right off. It should have an anchor instead. Until I find another screw that will work better, I placed it on the outer second shelf for now.
