This little gadget has proven quite effective for 3 weeks. The images are quite sharp, hard to define by what is against logic! Discreet, I appreciated the always have at hand the bunch of keys. The operating instructions are not quite right: I had to press the "Power" button to stop recording rather than the "Camera" button but once understood usage is pretty easy. The charge indicator never knew him tell me that the battery was full, regardless of the hours spent loading .. The big worry is that Monday (3 weeks after its first commissioning) the § #! & Battery indicator did not want to go out, or after a few minutes of waiting that triggered the automatic shutdown, nor hold down the power button or by inserting a paper clip into the "reset" hole. Result: it is off when the battery is completely discharged and since it is a brick: whatever the USB power on which I plug the LED remains off and I do not have access to the contents of the memory card inserted.
