Query: No way to clean

The premise for this toy is great and it sounds like such a wonderful idea, but using it reveals a few issues. The most important being the fact that the screen gets grubby-looking and there is no way to clean it effectively. Another problem is that the "pen" doesn't hold a whole lot of water, so the doodling fun doesn't last very long. The screen is quite small and is quickly filled with drawings. Turning it over to use the other side is fine the first time, but after that, both sides remain "drawn on" for quite some time. I would not recommend this toy.
