The bag is really worth the money. It is a place for everything [camera with lens (EOS 600D, 18-55mm), an extra lens, changing batteries, cables, charger, ...]. Mir is the bag almost too large. Processing is great (no rising seams, no fraying, durable zippers). Of particular note is the "pocket" that can pull, keeping the equipment dry well near a waterfall.
All in all a buy recommendation for the pocket.
For battery unfortunately I can only report negative. Compared with the original battery by Canon, the performance of the acquired here batteries from the beginning left a lot to be desired. The Canon battery lasted considerably longer and proven. From month to month the spread between the battery was getting bigger. Has hardly lost its power during the Canon battery until today, one could until a few days ago with the "fully charged", acquired here, just shoot battery 15 photos with flash. Exactly one year after purchasing the battery fails completely and can no longer be recharged.
All in all, DO NOT buy rating on the battery.
