Of course, one must not expect the charger to the processing quality of the original corresponds to, but it does what it should and that makes it good. I've even successfully charged the original battery it.
The two supplied batteries fit perfectly into the NEX-5N nothing wobbles, nothing stuck, size fits perfectly in agreement. They are noticeably lighter than the Sony original, keep far too little shorter. However, they have also only ever one charge cycle behind and batteries obtain their full capability known only after several charging cycles.
But even if the battery will hold slightly shorter than the original: Here you can get for a price that even 10-15 euros below that of a single original replacement batteries from Sony equal to a charger, which comes clear with 4 different input voltage sources 2 batteries that are fully compatible with the NEX cameras, including info chip, which shows the remaining charge level and free of charge. Together they hold guarantees for more than one original. ;)
Who plays with the idea to buy a spare battery should think about this bundle. Conclusion: very recommendable
