For the price, the performance is OK The battery is lasts as long as the original is far from. In addition, the battery is not used very much loses its charge, which does not happen too so strong at the original.
I forgive only 4 star:
positive:
- Fits like a glove in a 7D
- Invites without any problem on the original charging station
- Is recognized by the camera and shows tripping and battery strength
- Price
negative:
- Discharges very quickly if it is not in use
- Has not so strong by holding period as the original
- Can not be in a 7D register
I do not regret the purchase because I change the batteries frequently and at the price I actually expected less than I got. Therefore, going completely OK, although a few drawbacks exist.
I would buy it again.
