Nothing is more annoying than getting suddenly appear from the camera that only a little juice in the battery. It is nice that you can simply solve for the price of just under 5 euros this problem if one is going a little coordinated and the empty battery recharges each at home and holds as collateral in the camera bag for emergencies. The battery pack does not look "professional" from, as the original one supplied with the camera, but indeed like clothes make (like Gottfried Keller), with a hidden camera in the battery me is the matter, however. The nice thing is that really good the battery indicates the remaining capacity in comparison with the original Sony. The necessity to purchase a much more expensive original batteries I therefore see by my previous experience is not, because the camera is not so for eternity with me in action, and when the low-cost battery fails again, I can still get a new order.
