Yep ours are the same, rather play with rubbish than actual toys.

After the first post, we bought a really expensive fancy looking one and it lasted all of 5 minutes before they ripped the covering stuff off the post, it went straight back and we got the one we have at the moment which I cant pick fault with apart from they chewed the dangling ball of it in 2 minutes.

I want another one though for upstairs, seen one I like the look of. Its just a simple one post thing but its huge about 3 1/2 foot tall and 3/4 foot wide, it looks very solid and its covered with of one piece of really thick rope.
