We recently purchased the Xiaomi Yi action cam and we really like it. Its one of the best little cameras that we have played with in regards to quality and sound. In my opinion its a camera that is hard to beat especially for the price. The downside of that camera is that when you order it you only get the camera and nothing else. One of the biggest things that you may need is a water proof case. And thats what we have here. And for a pretty good price. Less then $10! Also the bonus of this case is with it you now have a camera that can be used with all GoPro mounts. And thats a huge bonus!
Take a look at the video. Hope you enjoy!
