There is a youtube video on it:
As stated above, it lacks the fancy features like wifi but camerawise, the main difference is it will only operate at 1080 pixels at 30 frames per second. This is still a great resolution and 30 fps is fast enough for most sports but if you need very fast action, say 60 frames per second, the resolution drops to 720 pixels. The
GoPro 3 for example records at 960 pixels for 60 fps and the hero 4 silver at: 1080p at 60 fps or 720p at 120 fps.
It's only going to make a difference if you are seriously into action footage and require ultra high definition at speed. If you don't really know what you are wanting to do with it but fancy having a go, it's a bargain price. It's better than aldi's camera which is darker and drops frames in comparison:
There is another camera, the Eyeshot HD Action Camera which has a wrist watch remote control with remote viewing, in case you use the camera as a helmet camera. There's a link at the end of the video above.
However, I have been in the IT industry since the 1970s and it is very easy to get sucked in by features. I was one of those in marketing when the term 'Paperless Office' was banded around. I have bought more printers than any other computer component. My best photos were on the cheapest cameras and my best illustrations were in Corel Draw version 1 and I still use Photoshop version 5. I took the time to learn how to do these things but found when there were loads of features, it became too much trouble to learn about the product.
Don't get sucked in by features. Learn how to use the simple products.
