How do you put 6 stars

Just perfect. Batteries perfectly compatible with my Canon 5D mark3 (chip recognized as if it were an original battery in the camera menu). The finish of 2 batteries is identical to an original Canon (apart from the inscriptions, hard to tell the difference) .The capacity of 1850mAh (the original Canon 1800mAh) is little difference with the original and seems to as long (to see if it lasts over time but given the price per unit, if it lasts 2 or even only 1 year this will remain a very good deal). Regarding the charger, it is a little plastoc. It's him that I take to the outputs because in addition to being lightweight & compact, I have no fear of losing or damaging it and in addition, it enables the burden on industry and lighter 12V cigarette vehicles. For cons, the output power is limited to 0.6A (1.2A for against that of Canon therefore provide twice the time for the load). All this deserves 5 stars but if we take into account more than the pack (2 batteries & charger) is 26 with free shipping compared to the price of a single original Canon battery 70 then yes, well worth 6 stars .
