KSH - You get the best result with the BF scales by averaging readings taken over several days - you can fluctuate quite a bit based on time of day, hydration level, etc. I like my BF scale, despite its flaws, because I have been trying to get away from putting too much stock in just the number on the scale, which tells you so little about your body composition.

It depends on your needs - sometimes, it seems far easier to just go by the way your pants fit!


Madisongrrl - From what I saw when I was researching them, they usually overestimate BF, at least for women (this is because they really only test the lower half of the body, and that's where most women tend to store the most fat.) So, your BF would generally be 5-7% lower than your scale reading.
