I have this battery for the video camera of my father ordered because the original batteries are MMN overpriced. At this price I would have given myself satisfied with slightly less power than the original battery. But this product has truly surprised me, because it is more durable than the Sony battery pack. In addition, the info chip is working properly, you always know how long you can still record with the battery. Therefore from me 5 stars, because this "cheap product" is better than the original !!!
