I love my Kodak Playsport. I use it to record my hiking trips on the Appalachian Trail and other outdoor activities. That said, the access doors to the SD card slot and the HDMI/USB out have always been difficult to open and frustrating to deal with. After my vacation, where I definitely pushed the camera’s 3m depth limit, I had to start using a flat head screw driver to open it (which from the video you will see is not a good idea). The technique showen in this video solved my problems.
