I love my Instinct Solar. I have never connected it to my phone though — I don’t want notifications or anything. I can manually take the workout results and plug them into my phone.
The solar part is really nice. I did a three hour hike in Colorado a few weeks ago (GPS off) and added like eight days of estimated battery.
(Disclaimer that I’m still new-ish to Linux)
I just went about a year between EndeavorOS updates on a laptop and uhh… it wasn’t happy. I just installed Kubuntu which hopefully will be more forgiving haha.
