I have a Roam and use it often. Its one of the originals and I did the firmware hack to upgrade it to a version 2 about a year ago. The company went out of business but they're back in operation.
I bought it because it was inexpensive but if I had to do it over again I would just get a Gopro. One really nice thing about Contour is the tube factor - it mounts easily and is low profile.
Here's a ride video from earlier this year. I edit these for fun after some of our rides.
