I gave the Vivofit 2 a 4 because of the syncing problem

I'm disappointed that I have to spend a lot of money on a Fitbit because garmin can't fix their sync problems

I don't know the cause of the sync problems - I suspect that it doesn't create a sufficiently strong signal to connect to my phone in order to save battery life

All kinds of sync problems, but the biggest problem is that any kind of motion counts as a step

However, o returned it because the person I bought it for didn't like it because she thinks a fitbit will somehow be better

Works great easy o use
