My first bike computer was Edge 520 and I loved it.
I tried navigating with my phone on my handlebar and I’ve broken few phones doing that.
Then I switched to Elemnt Bolt v.1
But I wasn’t very happy with the GPS accurancy and the constant beeps that I’m out of the track when I was on it.
Then I went back to the Garmin, 830, and I instantly regretted it. The accuracy was better, the screen was color and touch but the insistance of Garmin to force onto you every new gimmick they come up with, was too much. I waited for 840 to appear, and when I read the reviews I was sure it was NOT my new device.
Now I’m with Roam v.2 and I LOVE it!
