The idea is great, but the stylus isses a horror. Batteries drain really fast despite off. There are connection problems, software problems, etc. One can already almost guarantee that the pin after 2 years at the latest so zickt that you can only exchange it ... I also find it extremely cumbersome for small children's hands. The pen of Ting is better off by far. No batteries needed - is charged via USB cable is slimmer, lighter and handier. After all, you get usually sent to a new pen if you come with the Hotline no way to eradicate the Zickerei the pin. That is a small consolation.
