The title says it all. Am completely satisfied. The batteries I knew already and I've just ordered more. Use them mainly in my flash. So you get super clear, even during long flash sequences. But since SANYO batteries were already always very good. The advantage now is that I do not have to recharge all batteries again before making a large photo job. Even out of the package, I can work with it directly. Excellent! The battery boxes are stable and you can click together. Toll!
