to make it short: here you get something good for his money. And the batteries are even better than indicated, namely 1270 mAh (!) - So just like the original battery! Properly matching the parts are. The 4-way power supply is absolutely optimal, and thus you can save a lot of stripping tangle - home to the mains, the move from the cell phone charger (which is anyway this has). And in the car by car plug. What I like most that you can operate the device with battery operation (!). I use a battery to power bank, which I then connect to the USB port - works fine. If there was 6 stars ....
