Used for the Washington Ironman 70.3 and overall it was just fine once I got the nut that tightened by the mech on the course that holds the Garmin in place (before that it was very annoying and kept slipping down and allowing the bottle to come loose). The one thing, I have a Garmin 1040 and a 520. The 1040 seemed too big, so I opted to use the 520 with this rig. A small thing and mostly personal preference.
This was just what I needed. It fits great between my aero bars and can be adjusted to fit different size spaces. The hose comes long but you can cut it to the length needed very easily.
