I have mine mounted on a RAM ball on my MV riser between the handle-bar bases. It is on a RAM arm, so it is just below my line of sight when looking at the gauges. It is almost like it is part of the cluster with the exception that the depth of my vision is different to focus on it. My peripheral vision has no problem keeping me safely in my lane or avoiding traffic changes ahead while glancing at it. I wouldn't tailgate aggressively while trying to change a route, etc, but typical safe riding procedures give me no issues using the device to guide me to my next exit, or to check my actual speed vs my speedometer, etc. I really don't think the flick of my eye position from the horizon to my gps is different than to my cluster, or would be improved if on a shelf. That's my experience.
