> These must be good, I have a 520 after a 500 and lots of friends are ditching their garmins for wahoos! What is the huge improvement?
Simple to use via smartphone app. 100% reliable recording and routing. Syncing with Strava, Ride with GPS and others is automatic and faultless everytime.
I don't know anyone who has gone from Garmin to Wahoo who would now go back to Garmin.
The only fault I have found with Wahoo is that on maps you can only zoom in and out of your current position you can't move the map around as on a touchscreen. This is has only been an issue a couple of times in thousands of miles and it's easy enough to get your phone out on the odd occasion. It certainly wouldn't make me buy Garmin if I needed a new device tomorrow.
