I bought this cam for cycling and for a soon to be acquired quadricopter. And I'm thrilled. The Cam holds (almost) what it promises. It is robust, compatible with 99% of GoPro accessories (only the case is different because the power button sits somewhere else, and the dimensions of the lens glass is minimal different). However, there are concessions to the recording mode. The 60fps camera are interpolated, ie it is taken up with 30 fps, and taken every picture twice. Since such Actioncamvideos but mostly end up on Youtube, I did not care. I take on with 720p 30fps, and according to extrapolation Pass 9 hours of video on my 32GB memory card. The battery lasts just over an hour anyway. Also the camera's firmware is being actively developed, which may mean, however, that some functions are canceled out again. Yet - who spends more money for ne GoPro here, it needs to know himself - enough for me the SJ4000 all. And who attaches importance to real 60fps at 1080p, end of November 2014. should nocht wait something will present the SJ5000 which is which then can SJcam.
