You'll need to be an Amazon Prime member to take advantage of Prime Day deals. You can sign up for a free trial, which will see you through Prime Day and which you can cancel after 30 days.
There are some fantastic deals on smart home devices on Amazon Prime Day, including some brilliant price cuts on smart scales.
Amazon has slashed the price of Withings Body Cardio smart scales, which not only measure your weight, but also calculate your body composition, including fat and water mass.
Each member of your household can have their own profile, and the smart scale will recognize them as soon as they step on. Each person's weight will be synced to their profile automatically via Wi-Fi, and the accompanying smartphone app presents weight trends so you can see your progress.
Withings Body Cardio Smart Scale: $149.99 $105
Save $44.99 off a smart body composition scale this Amazon Prime Day. With Wi-Fi syncing, weight trends, and heart rate tracking, it's a great way to monitor your fitness and help maintain a healthy weight. This special Prime Day deal is only available on the black version of the scale.
These aren't the only great health and fitness deals you'll find on Prime Day. Amazon has also slashed the price of some fantastic sports watches from Fitbit. If you're already a keen runner or just getting started, there's something for you.
