easy to use, good quality when mounted properly and in well-lit conditions. Sound quality varies with the conditions and can be either tolerable or miserable. This camcorder cannot make miracles - if it vibrates, the picture will be corresponding. You'll be surprised but usual rules for shooting video do apply here, too :). It is waterproof but don't forget to use silicon grease each time you remove the rear lid. One of the drawbacks is lack of the screen - you don't know what you shoot. But, OK, it's a sport camera, not a real movie camcorder. Overall, it's OK and deserves 4 stars out of 5.
