Much nicer than expected from an unfamiliar brand

I ordered these to replace the aging Duracel batteries in my digital camera. I am always taking photos of my beautiful wife as well as when I am doing photo shoots so having long lasting batteries is very important to me and having them be rechargeable is a must since I don't want to have to keep buying disposables. I figured I could give them a try and even if they don't last too long I could always just throw them in my camera case as an emergency backup.

When they arrived they were fully charged but the directions sill said to charge them and top them off before the first use. The charger does not plug into the wall itself, it charges off of a micro USB cord that you must connect to your own rapid charging wall connector. I did this and within 10 minutes the lights on the charger turned from red to green, showing they were fully charged. I popped them into my camera (takes 4 batteries) and headed outside with the wife to take some shots and see how they did. After about 45 shots at maximum size and using my custom settings the gauge on the camera showed they still were over 3/4 full. Not bad at all for even the Duracel I usually use, in fact these had even a bit more charge left than they normally do. I proceded to take over 50 more shots and still had over 50% charge left. Very happy with these so far. I will charge them back up since it says you can do that 20k times and will take them onto my next shoot with my old Duracels as the spares. For the price, if these last for as many charges as they claim, they will be a fantastic purchase and well worth the price compared to disposables.
