@KERI, I agree with @AndBreathe on not betting the farm.
I always worry about these things that say they measure something as many on here will be aware. At best this sort of scale estimates the things they talk about. What they seem to do is to measure the current that flows when a potential is applied across a couple of body parts. So, they do not measure the things they claim. They actually measure a tiny, probably very noisy, electrical current whose value will be subject to all sorts of things. From that current they will use assumptions and algorithms to come up with some sort of estimate of the things they claim it measures. What they will never do is tell you the errors in the estimate which in this case I suspect would be quite high.
Not saying they are misleading or useless, just suggesting you not read as much into the output as the manufacturers would want you to. If you buy one, just, treat the output as interesting rather than definitive.
