    Good points

    • Good body fat accuracy.
    • Good weight accuracy.
    • Very good weight sensitivity.
    • OK to use.
    • Display OK to read.

    How we test

    We took readings from 15 men and women. We then compared the results with those obtained from a DEXA (Dual-Energy X-ray Absorptiometre) scan, a machine used in hospitals for determining body fat composition.

    Overall score includes:

    Body fat accuracy (25%) - How accurately the scale measured body fat.
    Weight accuracy (20%) - How accurately the scale measured body weight.
    Weight sensitivity (10%) - How sensitive the scale was in detecting incremental changes of 100g.
    Body fat deviation (15%) - Based on the reading that was furthest away from the DEXA scan. Measures how much it varied from the scan.
    Ease of use (30%) - How easy the display was to read; how easy the controls were to programme and push with your toe; feet positioning; and how stable the scale was to stand on.
