After receiving the unit, immediately unpacked card in and test. Have to an adapter for the socket used so that the power supply was ensured. Also, the photo shoot was tested. Now power supply off and on to the laptop. not 5 minutes and the machine switched off. Ok, I thought we invite times the battery only really on. After 4 hours, I closed again the device to your laptop. Pustekuchen all dead, why ?????? I bought a new battery and behold the device was alive again. Now times from in car and fixed to the wheel and went off the ride. After 20 minutes I took the device back to the laptop to the video sequences and stills evaluate. Was not there something about HD talk ???? Forget nix HD recording or playback !!!!!! Medium image quality is no longer! With regard to the operating instructions, so just something else. Also no German instruction here. So I was then initialy whopping hour tormented by the operator until I had set everything the way I felt it appropriate. But ........ gimmick for little more money is not. Can not recommend this device !!!!!!!.
