Very good battery, which is not original

The battery I bought for my Canon EOS 100 D. The stamina is indistinguishable from the original battery. Of course, it all depends on how much you shoot photos and the nature of those and if you used a flash or not. I have now shot so many photos with the battery and can not determine that it is weaker than the original. There is a definite buy recommendation and the price is excellent. As proven long-term performance of the battery, we seheh in about 1 year. In but am postiv daruf excited and do not expect a premature drop in performance.
