Rocked a Garmin a few years, now I'm trying galaxy watch 5 pro. Miss the week long battery but 2+ days is "ok", a lot less annoying then I first thought it would be.
Exelent integration with my phone is a big plus. (For instance the Garmin never let me respond to alarms from the Samsung clock app :/ )
I was really interested in the Watchy project, but it seems you can't buy them anymore. They just say stock of 0 and maybe will get stock this fall. Oh well.
