The finish is good, he is strong with aluminum hull and rubberized edges. The USB jacks are plugged correctly without play, the quality of workmanship. Note that you may turn it on by mistake, since it requires prolonged supports to turn. It happened to me this problem with a previous battery.
The big advantage, besides its large capacity, is that it stops automatically as soon as the charge is made. Reading the remaining capacity via the small LCD screen is also much more fun than a LED that flashes differently depending on the remaining charge (edgy dedication to sony)
Ideal for not crash but also smartphone camera on vacation or while hiking gps
Offered to date (November 2014) to less than 25, it's a good choice, especially when still see batteries with a much lower load at the same price.
