I opted for a Ansmann battery for my Canon 60D because of recommendation of several known and have to say that I do not regret the decision. Actually, I take the attitude to have all original Canon, but do not see, to pay more than three times for a spare battery and only to get the same quality. The battery is fit and sits in both the charger and in the camera as the original. The performance is emotionally similar to the original battery by Canon - as far as I can tell so far to three times more intense use (and associated recharging). From me a clear price / performance recommendation.
