1.0 out of 5 stars
Disappointing for me too, 18 July 2013
You are not able to tighten the clamp to the bicycle as much as needed when there is a camera mounted on. You can't mount it firmly enough and it will eventually move.
I use a ContourROAM2 which I think it's an average weight.
The video becomes useless since the camera vibrates too much and eventually the clamp starts loosing grip making it turn. If you find a few bumps on the road you might end up with the camera pointing at the sky. To clarify, I've only used it on the road.
I didn't read the reviews because I assumed that anything HAMA would be well built and you wouldn't find any issues of this kind. Well, lesson learnt!
