Save 34% on the RENPHO smart scale, now only $22.94 at Amazon

Grab yourself a bargain with this great deal on one of the best smart scales, now on Amazon

One of the best smart scales is on sale with a 34% discount on Amazon this weekend. The RENPHO smart scale did well in our in-home testing and we're pleased to see the price slashed by over $12.

You can view your data on the brand's accompanying app, with statistics including weight, body fat, visceral fat, muscle mass, basal metabolic rate, protein levels and fat-free body weight.

You can't feel the electrical charge and it's safe for most people, unless you have a pacemaker, medical implant or are pregnant. If any of these apply to you, speak to your doctor first before using one. Smart scales vary in accuracy but they are still a useful way to track changes in body composition, as well as support a weight loss or fitness journey.

Buy it if: You want to easily monitor your health and the health of your family. The RENPHO smart scale is easy to use and gives instant readings. The red numbers are easy to read against the black display. In terms of accuracy, the scales put our tester at 2 pounds heavier than the professional scales at their local gym, which is not a huge difference. We liked how the app was easy to use, giving useful intel on data gathered, including whether you fall into a healthy or unhealthy category for any of your 13 body composition readings.

Don't buy it if: Our only complaint is you might need to recalibrate the scale if you move it or turn it upside down, but this is easily done by standing on the scales with one foot.
