Anyone using these? If so, where did you mount it? I place mine right on the backside of my Puig DB screen but it's just barely hanging on to the velcro due to the shape of the screen. One good bump and I think I'll loose it. I might have to fab something out of foam to give it a flat mounting surface.
I keep mine in my jacket's left pocket. I take it out and hold it up to the sensor as I roll through; usually works fine.
