The ATC Chameleon action camera is a great camera. I would recommend it to anyone interested in outdoor fun, because the video we filmed was amazing.
The helmet mount works really well -- it sticks to the helmet like glue.
However, the handlebar mount did not work effectively. The screws did not go tight enough to fit the handlebar on my cousin Derek's quad. The handlebars on the quad are only about an inch thick -- not thick enough for the mount to work properly.
Because the handlebar mount was not fastened correctly, the camera flipped backward.
Also, anyone who buys the camera, which costs $79.99, should be aware that you need to purchase a SIM card separately.
The SIM card costs about $30, so that adds to the expense of the camera.
