This charger makes me a very good impression! The batteries have a similar maturity as the original ones. The batteries do not sit exaggerated firmly in the shell (could be a trace of solid), but the battery does not fall out! Status light = virtually USB output = awesome The dimensions of the charging station are pleasantly small that it easily should I fit any more GoPro Bag. The extensive accessories played a key role for me ... In my opinion, a great product!
