Overall I am happy with the cat tree and so are my cats.  They especially love the very top purches, which leads me to my only complaint...it wobbles a lot when they climb to the top and scares which ever cat is currently lounging on the tree.  My special needs cat did a swan-dive off of it from up high when my active cat ran to the top. It really scared her.  They are getting used to it though.  I hasn't been enough to keep them from using it.
