I use the cam drive for Motocross and we had the opportunity to have the first HD GoPro compete against the Sj4000 one weekend. High of the colors produces the SJ4000 is better, much sharper and more beautiful pictures! Well the battery lasts as long as the nciht from the GoPro but that one can buy an extra battery.
I would buy again, great alternative to the expensive GoPro system, also what concerns Accessories 1A!
