This talking scale truly is superior: it towers head and shoulders over every other scale we tried. It is accurate to within 1% of actual weight, and weighs up to 440 lbs (or 220 kg) in .2 lb increments. It speaks in a clear, audible female voice, and its digital readout is very large (1.25"). Its ample platform measures 14.5 X 11 inches, and it is ridged and textured to prevent you from slipping and sliding, even while you jump for joy when your diet pays off. Operates on 4 AA batteries (included).
