Strong point:
- Performance: the lights that flash, use is immediately (0.5 seconds) - against 1.2 seconds with the other even mAh battery brand Ca *** oven or other ...
- Charging time remains properly, 5h for my case with Energizer recharger also buys from Amazon.com
- Battery Duration: ok, I used a lot in the evening for flash and high speed syncho and no concern
- It has been 5 months of my purchase and I am always satisfied with these batteries.
