More than the product itself that perfectly meets the expectations I have to comment to experience a little adventure ... with good end. I ordered a battery of this type to Amazon Marfer who directed me to a seller "Marketplace". The order was very honored and the product was normally in original packaging, yes ... but proved defective (rare on a Sony product, but here can happen, proof) Small claim addressed to one and the other and after a moment of "floating". Amazon and Marfer ensured a perfectly satisfactory followed and made sure to meet me by sending another battery ... that her works perfectly. What emerges from this little mishap, it is very serious management Amazon has been anxious to meet his client. Bravo and thank you as a satisfied customer ... remains a good customer. PR
