The cap for the real writing tip is held in place with a rubber band and also includes therefore not flush with the rest of the pin from, but can be moved back and forth. The cap goes from extremely difficult and takes a lot of effort; Keep distance from the Tablet, otherwise the fly from a lap. With a pen I had to pull off the cap by force, would definitely be for a child not have been possible.
Cheap manufacturing - with five pins, a realization of one or another quality difference clearly. Can the many good reviews not explain. These pins wander in the waste before my tablet still takes damage.
For the PlayBook definitely not a purchase recommendation.
