Hey everyone,
I wanted to give some positive feedback as things work fairly well for me. All you can find in this forum is negative content, so I thought it would be fair to give my feedback as well. I don't want to downplay any issues you are struggling with, thought.
I purchased my VA3 Music in august as a fairly unused refurbished. I am pretty thankful that everything works, as there seems to be no warranty service by Garmin on products like this. So far battery has never been an issue for me as I am getting roughly 4 days on it using SW 5.4 and standard wallpaper. Tracking works fine but for hr on arm-intensive workouts. Also payments have been almost seamless for me. One time it somehow didn't work any more but a SW reset fixed it till today.
Today I noticed that Garmin even released a water tracking app so that this new functionality gets rolled out to VA3 and other devices as well. Good work on that and updates in general!
Only issue I really also had was skin irritation. I purchased the extremely pricy nylon band and since it is fine. BTW an I dependant testing agency in Germany (Stiftung Warentest) checked additives and softeners like BPA in a current Garmin watch and only gave it a mediocre grade. When I asked, they didn't want to tell what the issue was in detail. I could imagine it is in connection to the often posted irritations.
