Caveat: I am satisfied
I use 2 of these replicas battery for NP-FW50 in my Sony NEX-5.The purchase decision was somewhat irrational, the color white and decisive but then I was curious how the batteries in practice machen.Was to say, the batteries fit and funktioniern.
The NEX-5 draws much power and the result at the Weiss batteries is similar to the original batteries (with which I was not so happy), 250-300 photos are not a problem, moreover, it is difficult! The difference is in the price, for my 2nd original FW50 I had paid double the White Replacement batteries. So I am now partially with 3-4 batteries at the weekend and saw a saved me.
Conclusion: 2 batteries for the price of one. No Untrschied identifiable and beautiful whites are all.
