Barfly early adopter here. Big improvement over a stem mount. Before Barfly hit the market I had been using one of the accessory bar mounts; this worked fine for my 705, but didn't hold the 800 steady enough to use the touchscreen consistently. The Barfly has worked flawlessly; some have observed that the retention doesn't have a positive "click" (which is true), but I've never seen a report of someone having a Garmin eject when using a Barfly.
