My experience is mixed.
- The watch finds satellites really quickly.
- GPS accuracy seems pretty good within the towering surrounds of Milton Keynes / and California's South Bay. Which, aside from the roundabouts and bike paths, look a lot like each other.
- Charging is easy.
- Uploading activities is generally easy.
- I find the display works pretty well. I can read the numbers, that sort of thing.
- I like the programmable features, although you have to create them on the Garmin Connect website and download them to the watch.
- The watch tracks steps (if you're interested in that, heart rate, and sleep).
- I really like the activity reminder functionality that tells me when I've been sitting at a desk without moving for more than an hour. It's revealed how incredibly sedentary my life is.
The less good:
- There are lots of things that could just be a LOT better about the UI on the watch and the Garmin Connect website.
- And the data visualizations on the app / website.
- The Garmin Connect website is WAY less useful than the Strava website, which I'd been using when I was tracking activity with my phone.
- There's no native split/crop functionality. Strava has that worked out. Shame.
- If I go too long between uploads then the bluetooth data transfer times out before it finishes.
- The heart rate monitor isn't great.
- The sleep tracking really isn't great. Maybe I don't help things by switching time zones every month, but it's not great.
