Mediocre
Lightweight scratching board. When it's scratched, it immediately tips up; but of course that's also because of the rounded side. The cardboard gets damaged very quickly. The middle part is only 4.5cm high, so I don't think it'll take long before it breaks through.

The catnip falls right through
It's a great idea and the cats love it, but whoever thought the holes should go all the way through... all the catnip just falls straight out. Just give the thing a solid bottom.
