I bought one of the GoPro Sessions about 6 months ago. The Session is on the lower end of the cost scale for a GoPro and I would say it is worth every penny. If you take a few minutes and learn some of the features available on the camera it makes the editing process much easier. Like for example while the camera is running there is an option to tag portions of your video. If you simple push one of the two buttons on the camera it creates a marker on your video that makes finding and editing the parts you want much easier and faster.
I take mine with me every time I hit the lake and am considering getting a second one.
Like others have said there is a learning curve but like anything else the more you learn about it the more you get out of it.
I would tell anyone that is considering getting a camera to go for it. There are a lot of very reasonable cameras on the market (including GoPros) that one could get to try it out and still not have a huge investment into. In case it doesn’t end up interesting you in the end.
