A:Answer Depends on your needs... I love the Hero 4 sessions because it's very compact but very powerful. Here's my review on it...
This camera has been a dream. I'm an action news photojournalist and push this camera to it's limits in every way... light/dark, heat/cold, dry/wet. It has come in especially handy when I need to stick a camera under water in hurry. It's become my go-to camera in most situations. As for the reviewer who says "doesn't work most of the time", he/she obviously didn't read the directions. It is a very dependable camera and I'm planning on acquiring more. The new app features allow us to quickly pull 15 & 30 sec clips to post to social media to alert our followers of breaking news situations with quality video from the scene right out of the camera.
