Title: Worse than useless
Review: This body fat monitor is completely unreliable, which makes it worse than useless. On a few occasions I've used it twice in a row to check its reliability, and it routinely gives me two completely different readings (1% or more different), even though absolutely nothing had changed in the 20 seconds between readings. Imagine how different the readings will be over the course of a few days or weeks, purely due to measurement error. The estimate is also 4% different than the reading I got from a professional using calipers, despite my following the instructions accurately. I'm not sure what product you should use to measure your body fat changes, but it definitely shouldn't be this one.
