It's a good product but I feel it should be standard with the cameras as charging by USB cord is so user-unfriendly, I've never done it. On the product itself, one small gripe is that the battery fits so tightly that I struggle to clip it in or pull it our without some difficulty. You could literally swing the charger around your head and the battery would stay in place. If the design was open at the back a little more, it would be much easier to use. Overall though, good product.
