So that it could start right away on birthday, Dad has ever been worked and for his little ones are also the audio files for my Tiptoi Gift (first letter) and the books and games we definitely give for Christmas, or at least in the next few months , loaded onto the pen. In Windows 7 (64-bit), there were no problems with us.
While our little one had "technical" on his big day then a few problems, however the book fascinated him but so much so that he was no longer get rid until we arrived on the last page. He clicked each animal, the (unfortunately very few / 3?) Songs all repeatedly consulted, trying to answer the questions (although this does not always succeed, as he had sometimes not heard all the information about each animal before it moved to the question mode).
His mentioned "technical" problems existed for a fact that he did not really know how he could keep the thick pen, which sometimes went slightly on the accuracy. After Dad had but then eventually showed him that he must hold the pen like a regular pen (not like a wooden stake before Vampirpfählung and), we went equal better :-) He also sometimes had after touching an animal pen on the animal / the plant, then lifted him while explaining briefly minimal high around him sit up again, which of course meant that the text again and again went off in front of what he obviously did not understand. Here also helped no indication :-( But the problem only sometimes. He usually has only the images touched and lifted the pen again, as it should be.
Although he had just achieved so the manufacturer's recommended age, but he knew even that he can choose between different modes (knowledge, quiz, music ...) and this has repeatedly put into practice.
Conclusion: Beautifully designed and well thought out, keeps you awake interest and Fasziniation the child, the learning element is not already in question. Strong buy recommendation !!!!
