A nice Christmas present. The enthusiasm with young and old was tall. Lots of interesting facts with great entertainment value. Unfortunately we could not see much of it, because the pen has given up the ghost after an hour with cracking noises. Software used to date gebracht- other new batteries - unit "resets" - still nothing. So put the uncomplicated Amazon Exchange possibility to complete - now we are waiting for a belated Santa Claus. And I also noticed that one side with the label was printed only incompletely - are missing in each row, although only the first two letters, but a quality control has apparently not occurred here. Hopefully that was just a "Monday game".
