Pleasantly surprised and pleased with the XP C600 review. Although this is my first action camera it could be improved as a kit with a second battery and case offered by the C series cameras. I only used 1080p at 60fps - the quality is excellent. I've also used it as a car cam but have to mute it as the mic is sensitive to fan noise and other noises in the car interior. We bought the wrong batteries which were square on all sides. The C600 comes with a battery with rounded edges on one side. This is important because the square batteries deform the case and the battery door will not close. I ordered the correct round batteries. Since the C600 was a great camera I ordered (2) C200 cameras for my kids to see what the difference was in image quality, shake and lens adjustment. But they just received them, so I can't give an informed statement on any differences. The reason I ordered the C600 was the adjustable lenses to avoid camera shake. Let's see if I can buy a C600 or (2) C200.
