I have a digital scale and it works great. Mine has the fat% test as well which is'nt really accurate but it's just for fun (plus it does'nt go past 99%, don't ask how I know) Anyway, thew scale measures to 1/10ths of a pound which sucks because you gotta stand perfectly still until the numbers stop moving which is almost impossible for it to give you a fat% reading. If you move, it gives an error sign that kills me and I just give up.
Get the scale with .5 increments, not 1/10. I blame the scale for my obesity.
