These batteries are really up to. By already having this mark, but is more than 4 years (the performance is always excellent), and being very satisfied, so I returned to this mark when purchasing my camera. They really take the load well, I realized almost 950 pictures with 2 sets of 4 new batteries (the second game is still not empty) and when they had received a first charge. So I think that performance will still croitres.
It is a product that I recommend very strongly. Delivery is express, nothing to say, and as a bonus, they are delivered in a storage box which is very convenient for transportation.
