As I said, it is a clone of the GOPRO 3, which I use myself intensively for a year on the road motorcycle. Unfortunately, the connections of the SJ4000 may not be compatible with those of the GoPro, but the supplied fixtures are as stable and easy to handle. The quality of the camera convinces me it makes really good, sharp images!
Priced at around 70 this complete package is a real hammer! My opinion: before you spend more than 250 for a professional camera that often lying around or like is also lost, the SJ4000 would be a very great entry-level camera in order to make it clear at all times, how to deal with such a camera and if you feel like that process result to cut, and to make great films of it!
I have used them on a BMW, it does not wobble, keeps shocks and continuous rain from, delivers very good images in daylight and can be a great companion!
I would give 4 stars, 5 go against the giant price!
Here again two video links to this camera:
