I haven't received my Fly6 CE yet, should ship Friday, but I've been riding with my 12 CE since a few days before Christmas and have had no issues with recording.
I had the original Fly12 and the 2nd version of the Fly6 and absolutely love the smaller size of the 12 CE and the 1/4 turn mount. ANT+ connectivity is a nice plus as well. Video quality is much improved from the original 12 and image stabilization works well. All in all, I'm pretty happy with it.
The only thing I wish it still had is ability to transfer video wirelessly or view recorded video on a phone. While I never had to use it myself, I could see that being very beneficial in situations if law enforcement needs to see it.
