Devin Petersonwrote a review of Garmin Index Smart Scale on March 2, 2018
Familiarity: I've used it several times
This fits in seamlessly with your garmin connect account. The set up really isn't tricky at all as long as you're within the wifi area of where you'll be setting it up.
Everytime you step on the scale it will log your weight and record it automatically into your account. This makes it very easy to habitually use the scale and track in detail your work and other specs over times. Body fat Percentage with any of these scales is hit or miss but everything else is pretty accurate.
