Perfectly adapted to the Ascend Y330. Do not expect super leather for the price but not a bad imitation at all. Good protection for the screen by the stiffened panel; can be left hanging the smart deep in his bag without fear of damage. I do not use the screen protector films; by against the stylus is really what I needed, more accurate than the finger to the keyboard of numbers and letters. The plastic bearing shell (brittle ???) is bonded to the casing. From what I read, this method of attachment does not appear to be solid. However, the day when there will be more grip, simply pick with neoprene ... and it held good.
