I like mine so much, I'm going to upgrade to a 500 here pretty soon!! They really are not only highly functional, but it really is fun and useful to be able to see your ride data after an upload. I upload mine to both Strava and Garmin Connect.
I've been riding for over 6 years. Been commuting 17 miles one way,
have done 100 mile charity rides and have gone on long club rides -
one of them up Bear Mt. All of these without using a bike computer.
But last year; the club I joined(NYCC) asked that every rider have one
for the rotating pace line leads. I got the 200 and have been happy
with it. Comes with 2 mounts. A full charge is good for a couple of rides.
