zooplus Basics Wave Scratcher

I got the scratching wave as a gift because my cats love scratching boards, and we used to have the 'Kratzmöbel Welle', which isn't available anymore. I'm really disappointed with the new scratching wave. Zooplus has put a much worse product on the market, but they're still charging almost the same price as before. They've especially cut back on the size: the wave is now much shorter, the sides are just plain cardboard, and it's less stable.
