Love this version, however this is the third one I’ve had and battery didn’t last and after replacing batteries it only lasted a week

The batteries just died for the first time after 2 years 8 months of wearing it almost daily.

I bought it 2 years ago and the battery still works, incredible

I wore my vivo 2 constantly for over 2 years before I had to change the (inexpensive) batteries.

It doesn't nag me and the battery lasts about a year, so no charging needed.
