Some trepidation when buying batteries not made by the cameras manufacturer since I have heard stories about poor performance, loss of charge, catching fire and even damage to the camera. However, these replacement batteries seem to be well made and charge in exactly the same way as that supplied with the camera. I am using one for all my current needs and so far it has not caused any problems and seems to last as long as the original. This 2-pack seems to be exceptional good value. Should it fail sometime in the future I will update this review.
