I'll install it very soon, the reception of the product is still waiting .... By cons I have less chance than others, manual in English and Chinese yes but not French either on the menu . Basic usage is simple, once placed the SD card and the case turned on, the camera shoots at the slightest movement and for 1 minute after you stop and resume automatically (default) so it's going to hit but the options it becomes a little more complicated but with time ...
