I have a Canon camera. In order to be independent and to have a power reserve, the offer in Amazon was just right. Price was right and is much cheaper than the original CANON. After a little late delivery (delivery time was 1.5 weeks) I ACCU again loaded (in the Camera) and then used. I can not tell the difference for CANON BATTERY. Maybe there is a difference detected after repeated recharging, then I will again give or revise a rating in one year.
