Summary: I was impressed with the videos i've seen on Youtube, featuring the GoPro. I finally bought one and i was quite happy with the results. Unfortunately, mine was defective from the start and didn't worked properly. Sometimes, it worked fine but sometimes not. Got a full refund from Amazon. I plan to get the Hero3 in few months.
Summary: Love these cameras. I have had a HERO in both generations of HD and used them to create great shots for my work. Unfortunately my new, 3 Month old HERO2 has stopped working. After being in the loft. Had it stopped whilst underwater, or being strapped to a bike I would have understood for such a solid little camera to stop working whilst in the cupboard. So I am hoping to find customer service helpful and will update this after that.
