My kids love the books and games and I find them also great.
Unfortunately, we had 6 months to replace the 1st pin and by a further 1 year was the 2nd break.
This is not justified for the price, considering that the pin thus came to grief because of the small has always pushed too hard on the book / tapped. Something he should be able to withstand so.
And inexpensive spare parts there is not even. One has even the whole "carrot" - as they call my children - throw away. Not a good idea of environmental Ravensburber.
