Hi steven. Last month I was taking part in an event in wales and managed to fall off at 20-25 mph and break my collar bone. the camera was in my back pack and survived no problem as it's kept in a specific media pocket which is well padded and up around the neck area. That said you're right I was worried about that point too as I'm sure it's not shock proof or a sports camera but that's the worst accident I've had in eight years on the bike and I would hope the worst i would want to experience and it hasn't suffered at all. I see Sony and JVC are venturing into the sports camera sector to give go pro a run for their money so I might just look at one of them after they've had time to be evaluated.
