This battery provides power for professional requirements. Replicas, there are many whose power ranges from 20-70% then the original, as is the price, it is a gamble. Possibly an additional camera grip with eneloops or similar batteries in "AA" battery format is still an alternative, these batteries one need, where appropriate, for the flash. In summary, one can assume that the original of the LP-E6 reliable and very long time his ministry is doing (even after 2-3 years only minimal memory effect). Minimum withdrawal, 1 star there for the unfavorable price-performance ratio. This is for Canon's higher product classes but unfortunately quite common - who needs top performance must engage deeply into their pockets.
