I've been using the Go Pro Hero for quiet a while now, almost since the beginning they came out, the old model was crap with only 3 mega pixels, when they switched to HD, this little thing became a winner. I have done diving with the camera and took great underwater photos and videos, then I mounted it on several places on my bike while off road riding, mostly recording in 720, I really can't complain about any of the features of this camera, the battery last forever, if you turn it off after your session is finished, I recorded 16 GB of footage with the battery without problems. Having installed the back screen is a nice feature, but actually not very necessary, it is good, when you want to readjust the height or angle you shoot from, so you have an idea where you are. The only downside I can think of is the microphone on the Go Pro, since it is in a plastic case that is shock proof and water proof, the sound is somehow not very satisfying, if you need better sound you have to choose the open back cover, the sound will improve immediately, but not recommended if it's very dusty, it will mess up the camera at the end. All in all I've been more then satisfied with this little gem and most certain I would buy another one, if it got stolen... this is just my very own opinion
