A:AnswerNo, the bands for the vívofit 1 and vívofit 2 are designed different base on the module that fits inside. We do not recommend trying the incorrect band as this could cause the band to stretch or the module to fall out.

A:AnswerYou can see all your stats each day on the device itself. If you want to view a history of your stats (see more than just the current day), then you need to sync the device to the free Garmin Connect app on your iPhone, iPad, or computer.
A:AnswerGarmin only makes the bands in 2 sizes, small and large; there is no medium. Small fits wrist sizes 4.7 - 6.9 inches and Large fits 6.0-8.3 inches. You can buy the large ones directly from Garmin for $30; https://buy.garmin.com/en-US/US/prod532201.html
