This XL550 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 550 lbs (or 250 kg) in .2 lb increments. It speaks Spanish in a clear, audible voice, and its digital readout is very large. 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). #756550.
