To the point: I am 85 years old and cycle. The watch display is very hard to see indoors but bright and vivid outdoors. The sunnier it is the easier it is to see the display. Cycling mode works fairly well and does track route via GPS. It even allows me to pause workout and then resume, something that for long cycling trips is useful. The altimeter works when cycling to give false stair counts as it measures changes in elevation not the actual process of climbing stairs. The heart rate report shows me a continuous spread of my heart rate and allow me to see heart rate levels both high and low. I believe the sleep mode is modestly accurate and is more useful for trending data than highly accurate data. The fit is comfortable for me and HR works through the hair on my arms with no problem. It works very well with MyFitnessPal to plug food diary. It also connects well with my Withings WiFi scale. Only problem with 3r party apps is that I use Taction for BP readings and the new online site does not allow you to see or track your BP (I guess legacy customers can do this). The band last 2-3 days realistically especially if you are using GPS for an hour or more a day. Not a big deal for me as I charge it daily when I take it off to take a shower. The biggest reason to get a tracker with a display is that the info serves as a constant reminder to get up and go.
