I had one of these are a kid, around 10 or 11 years old. I did a few of the experiments, soaked up all the knowledge I could get out of the limited documentation, and then didn't touch it for a long time. When I got into electronics again (and for real this time) at around age 17, all of that knowledge amazingly still stuck to me. I had to look up how to actually wire transistors to be useful, but I remembered how they operated, and what they were capable of (except for the book didn't cover amplification). This is one of the reasons why I think kids should be exposed to as much as possible. Even if they drop it later, if they ever pick it back up, they will be significantly more prepared, and hopefully can learn the rest on their own
