Negative Positive
Title: Inaccurate and Pointless
Review: Tried one of these out at a health fair. The guy said it has a 4-5% margin of error...that is a lot IMO. There are a lot of factors (e.g. recent eating activity, recent exercise, skin temperature, air temperature, hydration level) that can impede the electric currents of these kinds of devices, so I wouldn't be surprised if the margin of error were even larger. But that didn't even matter because it wouldn't give me a measurement, it kept giving me an error. The guy said it usually occurs if you are too lean. So apparently it only works if you are w/in a certain body fat % range, and even then it's essentially just giving you a 10% range.You are better off getting a caliper (cheaper and 1% margin of error).
Is the review positive or negative?
