Of course, was curious to see how the 'No Name'Akku compared with the Sony Nex 5 works, but my doubts were not appropriate. The 'Bundle Star * Quality Battery for Sony NP-FW50 with Info Chip' fits like the Sony original battery perfect in the camera bay of Nex5 and in the original Sony charger. The battery pack is easily recognized by the Nex5 and the info chip works just like the original, ie, charge level indicator works exactly. After 250 images, various image processing with the display, several movies and since about 7 days in the camera shaft has the 'bundle Star battery' still 12% capacity. What you want for the price even more. The 'Bundle Star Battery' is definitely a full replacement for the Sony original battery, almost a third cheaper so more than just a second battery. Conclusion: - Value for money, excellent - Fully comparable with the original - Fit with camera + charger perfectly - Fast delivery within three days !!! I can 'bundle Star battery' only friend.
