I bought 2 together. Initially, they worked like the original Canon, but after 5 months, one drains suddenly while it shows that it's full! And if I happen to be recording video, the entire video is lost. The store told me that they don't provide a 6-month warranty and only cover them for the first week if there is a problem. The second one still works as it should. I used them the same way, so it's strange that one is still at 99% while the other, with the same usage, has gone down to 65%. If you need them exclusively for photos, it's an economical solution. However, if you plan to shoot video, which consumes a lot of power, I would recommend investing in an authentic battery. Especially for important occasions, like weddings, the risk of losing a unique moment with this battery after a few months is high.

Fast shipping of the battery. Unfortunately, its duration is about 70-75% compared to the original battery, but its price justifies it.
