Easy to setup. Some features took a bit of digging to find and modify. The default screens appear to be set to show all the new features and gadgets. Mostly not for me. Buttons are not as intuitive as the last model. I have had several models of the Edge 500 series. Long battery life. Good display. One I figured out how to change the screens, I was much more satisfied with this Edge. I don't think the grade works very well at all. Jumps around too much, is slow to respond, and isn't that accurate. My last Edge was more stable and seemed to agree with online mapping gps apps. Comparing my Forerunner 965 to this Edge 540 showed discrepancies. Most of the time the Edge was low by 1 to 3 degrees and response was slower. However, there were times when the Forerunner was lower. Go figure. Oh, I really dislike the ClimbPro. Way off as to start and end of climbs. And the pop-up is too big and stays on during a climb, blocking the view of more important data. I had to search how to turn it off and did so. I don't see me ever using it again.
