I have this shell precaution taken because of an offer ever for my daughter, who is to get to her next birthday also their own Storio. When my son is already in use (in blue of course), and I can both on device and envelope only positive things. The case provides a good protection, can all major ports and functions more accessible and also looks nice. The set-up function is not perfect, but is used now and then like. I would still recommend in addition a display film, since it is precisely small children do not always particularly careful to deal with their stuff and despite the envelope can Storio in use fall off times or be scratched by rough to use. Here we have chosen the favorable serve their purpose very well, in combination with the envelope sufficient protection.
