I used the 800 on the century ride I did a couple weeks ago. It worked flawlessly. I'll be getting a new powertap wireless to replace my wired version so I can get power displayed and downloaded from the Garmin. I brought it down last weekend with me to use the GPS routing feature but our ride was sleeted out. It will take me several good rides to organize the displays to what I want but I'm happy with how it looks while riding. The info is easy to read.
