I've since given them to a nephew and I'm happy to see he gets just as much entertainment out of them as I did. Plain wooden blocks can represent almost anything. There are no batteries or moving parts to fail. Mine got a little bit of surface wear but they still work just as well as they did when they were new and small children don't care about perfect appearance. I wouldn't be surprised if they end up getting passed down to another generation and continue to provide the same entertainment. I highly recommend this kind of simple toy for young children.
