Extremely valuable! My children learn to read, write and do arithmetic, combine this child-friendly panties with Barbie figures and take it as Coloring for wallpaper. I was skeptical at first, because the color is to be harmful for children green. But I have convinced myself quickly to the contrary, because the device fits comfortably in your hand, is extremely versatile (dog collar, tie, rope, curtains, ...) and just fun! I really can highly recommend, is pleased about each child three times more than a tedious, pointless Gameboy! Tip: It is best to order three, then you can braid it a pretty bibs! :)
