As good as GoPro but much much cheaper

I wanted to get a GoPro for my motorbike, but when I checked the price-tag for the original GoPro it was too high. Then I started searching and came across this one. It does everything GoPro does and it comes with a ton of attachment, so you don't even need to buy an extra accessories kit. I literally cannot think of anything you can't attach it to. I use it with 64GB card, which works with no problems. It comes with two batteries so you don't need to worry about the power. Also each battery takes a long time to empty.
It has a loop recording mode which kind of confused me at the beginning but once I turned that off it was recording forever.
Like I said I am using it on a motorcycle in a city with a lot of potholes, and it doesn't seem to be bothered by shock or vibrations so far.
