I've used it once or twice and have initial impressions
I have broken a lot of the plastic mounts so I figured I would give this a try. Instead now I just break the GoPro Housing so it didn't really solve the problem. Nice that it is mountable to many surfaces. The product does not come with an allen wrench to tighten and loosen the screw to release the camera... that blows.
These camera are great. Resolution and pic quality is great for the price and the new upgrades here are awesome. 120fps for super slow motion, 3 options for framing, faster frames per second on still shots.... Hell yeah! Combine this with the viewfinder backpack and you just can't beat this pocket sized camera.
