Ordering and delivery is 5 stars. 
The quality and value of the cat tree is good. 
However, There are design flaws. There is no easy way for the cat to move from level 3 to level 4. Level 4 is the most important level in our case. To use the CatTree they way I want, I have to buy material to install some addition. Also Level 5 is too small for an adult cat.
