I have only had this for a dozen rides. I like the page that shows all of the stats while you ride. The riding I do is all rail trail, so the slope incline does not show accurately. Sometimes I think it is the tree cover and poor satellite pick up. I like the connection to my phone because it helps me decide if I need to answer or not. I like the side buttons because I can scroll through the different screens better than a touch screen.
I love the new features from my previous Edge 520 Plus. Grit and Flow w/JUMPS is fun on the MTB trails and the ClimbPro for climbing on my gravel rides. The display is easy to read.
I bought as 530 was having problems dropping sensors come to find out 540 has same issue of dropping sensor is it goes into sleep mode. Not always preferable to have to shut down and start Edge 540 during a race.
Great battery but I have had a lot of issues with it connecting to HRM and power meters. My last ride it wouldn’t connect with anything, including my phone to download my ride. Great when it works, very frustrating that it doesn’t always work the way it should.
