Bought in September 2013, beginning in 2014 after a few uses, a battery charge more only 30% capacity, impossible to use. Even leaving the charge for a day, the charger light does not turn green and stays flashing red. Once put into the case and consulting in the device menu this one indicates the load at 30%. I think it must be that of a fault on a battery and must not jeopardize the quality as the other works perfectly. Having had contact with the seller who sent me an email confirming that the batteries were secured, this one asked for my shipping address for me I suppose another return, congratulations for the professionalism of the seller is to recommend
