The film is in my view well suited for this device. It is extremely scratch-proof (unless one is busy with sharp objects turn around), it hardly takes fingerprints on and it does not produce glare or other reflections and does not hinder the operation of the Storios especially. In addition, they can be clean and free of bubbles attach. Stating that she was not fit but too small, I can not personally confirm great. In the apparatus of my child, the film fits perfectly from the left to the right margin. Only the top and bottom is a little air, but what is likely to be less than 1 mm (overall) and neither bothers me my dwarf. Because the display of Storio lower than the rest of the device, the attachment is not as handy as a normal tablet and the film may be the "inner" sloped part of the display frame slide. Here, then, a steady hand and a good eye is already asked. However, the is yes then the construction of Storios and not on the quality of the film.
