The key to getting consistent results with this device is to measure under the same hydration conditions. My suggestion: wake up, urinate, and then weigh and body fat analyze yourself using this device. While it's true that this is your most dehydrated state of the day (thus resulting in your lowest possible body fat percentage) at least this way you can track your progress consistently. My body fat percentage goes up like 3% after I've rehydrated myself in the morning (I drink a lot of water).While I can't testify to its exact accuracy, it definitely gets the trend correct. As I've lost fat (as measured by looking in the mirror, weighing myself and strength gains/maintenance in the gym during weight lifting), the analyzer shows a decrease in % body fat. The device also picked up periods when I've lost muscle (as measured by loss of strength in the gym during weight lifting). It feels pretty accurate at picking up small real changes.I have a set of calipers, and I find them to be kinda useless because I'm not trained in using them and you can only reach some sites of measurement. The Omron device is much more useful to me than the calipers.
