Here is a test video I made using the Revl software.
This was shot in 1080p 60fps but has been compressed by YouTube so looks pretty ordinary
I have already had mine replaced under warranty. Apparently a manufacturing issue was the cause of the gimbal ceasing to work. A ribbon cable had come loose.
The Revl app for Android is lacking functionality but they are working on that.
I sync my Revl to my Trace device and the two work well together. The Trace having a similar auto edit function achieved by uploading the Revl footage and Trace data to a drop box and the two combine to create a highlight reel with data overlays. (This dropbox functionality is a bit hit and miss. The Trace device Mac software if much better)
Sample video here. Note again this been compressed by YouTube so the quality is a bit poor. As are my kitsurfing skills.....
