Navigation is currently broken (but it’s never going to be any use on a small screened B&W device with no mapping) so not much of a loss.
Screen definition and visibility, even in bright direct sunlight, is brilliant.
I’m liking the BT link to my phone for upload to Strava and text/call notifications. Strava segments are actually more interesting than i thought on solo training rides – occasionally you want to really push yourself and its a good way of doing it.
Downside – it looks as if Garmin have made a shit decision and prioritised size over battery life. At the moment it looks as if you only get their 15 hours spec if you’ve nothing connected to it. Add a few sensors and that drops significantly.
I really like it.
