I bought a xiaoyi Yi dash cam last week. It one of the top 10 best dash cam in the market which I found that on google, http://10trumps.com/best-dash-cams/#Xiaomi-Yi-Dash-Camera
unlike other dash cam in the 1080p model, it is very reliable in recording for a long time, so I strongly suggest you to check up this device if you want to get one recently!
