Not always easy to ask, the vivid blood cells, but being able to have 3 copies allows to train in case. Protection and good visibility is maintained still we manage to correctly position on the screen, the same exist on Ipad 4, same, very good readability with Retina and a warmer touch than directly on the glass. Warning I tried other models, and great brand, bought more expensive anti-reflective. On Retina quality is lost.
