My wife bought a fit-bit when she got her Turbo 2 and she had problems with syncing it. She returned it the next day but she still wants a fitness tracker. Which ones work or don't work with Turbo 2. I've read reviews for a bunch and they appear to all have that problem represented equally. Besides Fit-Bit Charge HR, she was interested in Vivo Fit 3 from Garmin.
