Good quality cover, plastic buttons too hard, perfect key fallback mechanism. However impossible to pin because the imprint hole and that of the mechanism are not quite opposite. Solution: Insert the impression in the mechanism and have a drill adapted throughout using a dremel. Problem # 2: The battery contact (-) to the circuit board is not made even after the contact legs twisted in all directions. Solution: recover the metal support the original battery shell. Warning! NOT pull the carrier out. It being returned with force a plastic axis, it must instead be supported by BELOW with a tiny screwdriver to remove it easily. I do not need to perform any manipulation then reset: the plip is operational on. Review: 5 stars for the price / quality ratio and 4 stars for convenience which may put less of us handymen.
