I did some reviews on it and I decided not to buy it. Reason being was battery life. You can not replace the battery. I ended up going with the drift and love it so far!
I work in a shop that sells them. They are made for a Moto then recharge. Batter only last 2 hours in the best conditions. Great video and super strong but not made for a whole days riding. Go with the hero 4 silver. By far the best bang for the buck.
May I suggest looking at the Wasp brand...Very durable, I have had one for 3yrs now and love it. I get 6-8hrs of recording in the winter cold and 8-10hrs in the summer heat. Check them out..
