This shell is not the strongest or the most protective, but it served its purpose perfectly. Like the Smart Cover for Apple iPad, opening or closing the cover wakes or in stand the phone; it's just perfect and extremely convenient. The white color does not seem to age at this time (2 months). The only potential weak point in time, it is precisely the fact that it is flip type, where the flap is folded for closing gives an air of fragility, I feel it will fall one day because it is not a comprehensive mechanism as a Smart Cover. But for the price, this case is practical and can be easily replaced (requires unclip the original shell of the phone because this really shell replacement of the phone, it is part of the phone). Nothing wrong, that's good!
