I've had patchy success with the remote. When I had a camera mounted on the rear quarterpanel of the bike, the remote just wouldn't trigger it unless i was off the bike. Obviously the signal isn't strong enough to pass through human!
That said, a great feature is that as I have 3 Drift cameras in total, they can all be triggered with just the one remote. Which is a GREAT feature. So when it works, it's fantastic!
