Since the purchase price was not very high, I thought that I 'risk' times eingehe and this accumulator order here. I have to say I was not disappointed to date. The battery fit (like the original) perfectly in the device. After a few charging operations he had (s) reaches a capacity that I could not distinguish from the original (as the original was new). Meanwhile a lot of loading operations have passed and the battery can its performance still provide / retrieve, as the first day. A good product !! Delivery was very fast, so thumbs up!
