Drift have been kind enough to send me over their latest, cheapest and smallest action camera - the Drift Stealth 2. In the video below you can see my full review.
After using this camera for a few weeks I can now say that it has supplanted the Contour Roam as my favourite helmet mount action camera. The mounting system is more flexible (it allows tilt), the camera is smaller, lighter and performs much better in low light.
In my opinion the Drift Stealth 2 would be an excellent commuter camera for cyclists - the three hour battery life, water resistant case and recycled video function make it idea for this purpose.
