A very good idea, unfortunately, poorly implemented

All the advantages and positive aspects of the product can be read in the meantime many other reviews. Children really have a lot of fun with it and it is a very good idea, I think. I've noticed the following weakness of the pen. It's in the past 3 years, the second pin, which thereby breaks down, it just gets dropped off the table or sofa. For a child's toy, a no-go. As a result, the sound disappears completely. So the pen has a very weak audio implementation. The only way that then remains is to connect the headphones or external speakers portable. Thus, the fun factor drops drastically. So let them play with it alone under any circumstances children. Even the 6 years it happens sometimes that the pin is falling down, which is fatal. When quality can I find the price way too overpriced.
