Summary: Amazing unit. We are using this on the OUTSIDE of a turbine helicopter doing aerobatics and during test flights. A gopro would never hang in there and would cause some disruption of airflow. Good vibration resistance in the unit, but the base has too much clearance with the locking unit. You have to shim it or develop your own mount for the kind of activities we do.
Summary: I had used a Replay XD 1080 and was going to get one but when I saw they now have an even smaller model I jumped at the chance. It's not cluttered with a lot of features, just select 1080i or 720p and hit go. The metal housing is great and the form factor is way better than a GoPro for use as a helmet cam.
Summary: So far I've only used this camera once and it worked awesome!! It was an overcast, cold day with a real fine mist/fog in the air and about 27 degrees. I mounted it with a long arm suction cup mount on the drivers side rear quarter panel facing forward. The video image was very stable and the color and clarity was spectacular.
Summary: This meets my expectations. It takes a little time to get used to the controls. It only seems to stay ON when the SD card is installed. Can't keep it running without it. But it works fine and I have several ideas beyond my original intent for using it.
