Which Withings scale is right for you depends on your needs, as different scales cater for various preferences. For example, the Withings Body+ is best if you want to collect all your health data in one place. The Withings Body Cardio, however, is the one to look into if fitness is your ultimate goal, as it can indicate your overall cardiovascular health. It is heavy and more expensive, so although it is more premium, it is not for those that want a lightweight scale.
