Easy to use, great screen, great unit!

The first thing that stood out to me when getting this computer was just how easy it was to set up. Having already been in the SRAM AXS ecosystem made things pretty straightforward, but I don't think it would have been much different had I been riding Shimano. It paired right up with my drivetrain and all of my sensors (PM, speed, HR monitor, etc.) While getting everything set up, I really liked the clear, bright screen. This stayed the case while out on rides. It's really easy to view. Being able to easily modify the information shown on each tab/screen that you could cycle through made having the data I needed easy to view and navigate to. The touchscreen makes using the computer easy and works with sweaty fingers and gloves just fine. While on the ride though, it's nice to have the side buttons for more accurately cycling between the map and ride data. I really like the navigation. The notifications for upcoming turns were clear and given with enough advanced notice that I never blow past a turn. It's a small feature, but I really value the chevrons placed on your planned route to show you the direction. This is especially helpful when you're planned route has repeated or backtracked sections. There's a ton of capability here that I have not yet fully explored. On yesterdays ride, I was really wanting to see the "distance remaining on route" but hadn't selected to display that information. Luckily, it's capable of displaying that and I'll have that changed in the settings for next time. Battery life is pretty solid, but if you leave the display on the map the whole ride, it sucks the battery life down faster. You can easily put the display to sleep to conserve the battery, which is nice. Overall, I've been very happy with the computer!

Beautiful screen, fast, great unit. I like it better than my garmin 1050.
