I would have given 5 stars for this almost perfect APN. But everything is spoiled for a battery history. Indeed, a dedicated software (version 1.2), added in April detects whether a generic battery is used and blocks the device in this case. The battery "approved" replacement costs 50 while generics are about 10à30. The "safe" argument does not hold ... Panasonic generic batteries are sold all over the world, they are of good quality and do not pose a security problem. It's just a question for Pana. to make a little money on the backs of its customers. Shame! Ditto for the connection: when you walk, especially do not forget to bring your cable to connect to a computer or TV. Indeed, the decision of the case is not a standard USB, but a specific Pana. ! Write to Panasonic-France and an asso consumers to protest. Do not get or do soon, when you will buy a car, the manufacturer will impose its brand of tires or wipers! Imagine a few other scenarios!
