Battery life is great, I can use it more than a week exercising 2 hrs everyday and wearing it all the time without worrying about battery, but I do most of my training indoors

Battery Life is excelent

I say the feature set on the V800 can't be beat, especially training load on the watch itself, and the battery life is awesome where I can go a week or two without charging; try that with an Apple Watch.

The battery life is great, it usually charges enough when i sync my workouts

Great battery life - friends with alternatives to the same basic set-up have been in awe of my battery

Undecided as to which one I will use after I get up in the morning

The HR monitor in the water appears to be accurate as well as when I'm cycling

It does seem like they plan on supporting it for quite a while so though its expensive I still feel like it's worth it.
