SJCAM SJ8 Pro vs. Eken H6s 4k as dash cams

I use on a regular basis a Addkey Dashcam, bought from their AliExpress store http://s.click.aliexpress.com/e/bDkQrTDI I did this video to compare the image quality between this 1440p cam with two similar priced action cams, the SJ8 Pro is somewhat more expensive and the H6s is a bit cheeper. I experienced some image issues with the H6s cam, unsure if its the processor in it or some malfunction with the memory card. I will have to investigate it further. Apart from these issues Its a great compact camera, but lacks some of the features on the SJCAM (such as touchscreen and 60fps). Cameras are bought from Ebay.
