While not as feature rich as either the HD Ghost or the Hero3 (no remote, slo-mo, or fancy high-speed photos), the Roam 2 captures high-quality footage at half the price. The on-off switch slides forward and back, which made it easy to operate even with ski mitts on, and a beam of light pinpointed exactly where I aimed it. One knock: the Roam 2 beeps like a cardiac monitor when low on power or memory, which got annoying. But the camera made up for it in toughness. When I accidently backed my Toyota Camry over it, the Roam 2 lived to beep about it.
SPECIAL FEATURE: The lens and mount both rotate 270 degrees, so with a swivel and a twist I was able to film behind me without shooting upside down.
VERDICT: Simple and solid—great for folks on a budget.
