Bought there over a year and a half, this battery is used alternately with the original one on a Samsung WB500 camera. Their maintenance charge, every two, is consistent with their theoretical specification. I took some pictures from thousands of hundreds for days without being in trouble. This battery ABC Products seems almost as good as the original Samsung.
I did not think for extremely cheap price I would have such a powerful battery.
Thank you to ABC Products for its product, and Amazon.com for excellence mailing service. Speed and quality, nothing to say!
