I looked away an envelope for my grade 3 Front, price-performance are fully in order. The original back cover is removed and replaced by the cover. The lid goes on it a little strict, but he considers reliable. Because of the size allows the cover closed a bit carried away and forth, but that does not really bother. The criticized in other recessions missing recess the lower button on the inside cover, made no problems. I read a lot and the staff in his left hand holding, bothered me the most is that I after an hour had not a pleasant feeling through the lid to hold the phone on. But this is a very specific problem. Toll I found that the cover not plotting and anyway large phone makes not unwieldy.
