Packaging and prompt arrival=5 stars. Over all appearance=4 stars (exactly as expected). Ease of putting it together=4 stars--no problems, directions very clear. But, in terms of function: the jump from the fourth tier to the top is very awkward, even for my more agile cat. The jumping angle and space just do not work that well. Plus, the house is very small--my two can fit but it's really hard to do. They go into the house, stay for a few minutes and come back out. Also, the space between the base, tier one and tier two is so short as to be pretty useless for lounging. I would return it, but "it'll do"--once it's put together, it's a pain to deconstruct. (and, of course, I would then need to buy another one). Functionality=2, which puts overall usage way down to 3. I would not recommend this and will probably be purchasing a replacement sooner rather than later.
