It's a great size and our cats love it. The major flaw is its longevity. The cats reach up or climb it, so the top half wears off. After a number of months, the top will be worn down and the bottom half perfect. The fittings are different on the top and bottom of the post. So there is no way that you can unscrew the top and bottom and swap them around, thus doubling the lifetime of the scratching post. This is both costly from both a financial and environmental waste perspective. So you are paying double what you need to! It looks like the company has made this decision on purpose which is very unethical.
