Good cheap alternative to the original. Since the expensive Sony DSLRs and also the XDCAM camera, no external charger more is settled - for whatever reason, in a device price of just over 2,000, - probably remains the Sony philosophy - this is a very good alternative for example the Sony a7 / A7R / A7S. I'm very satisfied with the two batteries. Now expect not necessarily the same quality and durability of the original Sony but for the super low price you can buy 4-5 batteries.
