It's working great. Love the display and all the info you can look at at one time.
I have the sensor on the rear chain stay (I think that's what it's called). In order to mount it there, you need to swap pins inside the sensor (my buddy did it for me - I can get more specific instructions if you want). The instructions don't tell you any of this - not sure why.
I did install the cadence sensor on the rear chain stay and crank arm also - and even though it's closer to the computer, the data seems to drop in and out. Not sure why - might just be a bad battery.
