Garmin Index S2 review

The Index S2 is built for people already living in Garmin Connect. It measures weight, BMI, body fat percentage, skeletal muscle mass, bone mass and body water, and it syncs over Wi-Fi straight to your Garmin Connect account, where weigh-ins sit next to training, sleep and activity data from a Garmin watch. The high-resolution color display shows a 30-day weight trend and, with Wi-Fi, a weather widget. Garmin says it supports up to 16 user profiles, each syncing to its own account, and runs up to 9 months on batteries. A weight-only option lets anyone turn off body composition data they do not want recorded, and multiple daily weigh-ins show how weight moves through the day. Garmin notes that people with pacemakers or other internal electronic devices should not use it. At $199.99 it costs much more than Wyze or Renpho scales with similar metrics, so its value depends on whether you already use Garmin.
