With action cams it depends what you want it for, Personally I don't use my cameras to record for posterity, I just like to record everything for my own use in case of having an accident to hopeful prove I was in the right, for this reason I need no features apart from loop recording. In the past I paid out for a GoPro and riding back from Somerset it fell of the bike and I lost it (Iv always had visions of someone finding it one day and watching what's on it and seeing it fall of my bike and bounceing through someone's windscreen ) , as it was expensive I was REALLY peed of so all I buy now is the cheapo Chinese GoPro copy's for £9.99, features are very basic but they record and in HD and Iv yet to have a fault with one. I brought 10 of them and have put 2 on each bike (front and back) and 2 in the car and including buying memory cards for each Iv still spent less than half the price I spent on my original GoPro and over a year on they are still going strong.
