Q & As

Rated 5 out of 5 by 3 reviewers.
Rated 5 out of 5 by Great scales These are great scales, if not a little scary when you see the results. You can have up to five people's results and you can review again once you've weighed. Takes a bit of setting up but fine, don't understand all of the measures yet e.g. Bone mass but all the others are good. Nice looking and neat size. I would recommend them 04 August 2015
Rated 5 out of 5 by Highly Motivating !! Fabulous scales, great design and price for the information they provide. Once you input your gender, age and height simply stand on them to obtain your weight, BMI, body fat percentage, visceral fat level, body type, bone mass, muscle mass, basal metabolic rate (daily calories needed when at rest) and water percentage. All these readings provide a more accurate picture of health and fitness than weight alone and are particularly motivating when following a weight loss/exercise plan as they show amount of muscle gained and fat lost when weight remains unchanged (muscle weighs more than fat) The best time to weigh yourself is before your evening meal and keep this time consistent as water mass varies throughout day (We wake dehydrated and this will produce higher fat percentage readings) I have used these scales for 4 months now and have obtained consistently accurate readings which help keep me on track and motivated at the gym. Highly recommended particularly for those who are resolved to improve their overall health :) 03 December 2014
Rated 5 out of 5 by Best scales I've ever had. Although you can never really know how accurate all the other things like BMI, metabolic age, visceral fat levels are these scales really are an eye opener, making for some unpleasant reading at times. A reality check maybe! They do just weigh you if you use the weight only button but it's more interesting going through the full nine categories as it takes no time at all. Very neat looking, almost like a computer tablet!! 22 June 2014
