Today my 2nd edge dropped from my bike as I rode at high speed. I lost it - even though I had added the more robust mounting after I lost the first one. I took extra care to snap it in, used fresh mounts (they wear out) and it STILL fell off. What a piece of junk.Garmin Edge 205 GPS-Enabled Cycling Computer
