I took a bit of a chance on these. Very cheap but claiming recognised internals. It wasn't until the check out that I saw the delivery times and only their best efforts would get them here before my trip. They arrived the day BEFORE there estimate and were pretty well fully charged. + points - They performed well in terms of number of shots so did the job - point - They showed battery situation on screen but died very soon after I was down to one bar. In reality, as I had 2 plus the original I had no issues.
