Good points

  • OK body fat accuracy.
  • Very good weight accuracy.
  • OK weight sensitivity.
  • Easy to use.
  • Easy to set up.
  • Display easy to read.
  • Controls very easy to operate with a toe.
  • Has Wi-Fi connectivity.
  • Measurements can also be displayed on the app and stored for later review (also works without the app).
  • Identifies previous set users (although if more than one user has a similar weight measurements can get confused).

But

  • Problematic establishing Bluetooth connection with the app.

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.
