I've used this scale and i've found some serious flaws. First, besides the weight measurement, none of the other readings are TRUE readings. All the readings such as Fat%, Body Muscle%, Water% is ESTIMATED. When you first get the scale you have to enter in your height, age, sex, and level of activity. The level of activity is the most important factor, basically you tell the scale if you live a normal life of activity, moderate life of activity were you do some excercise or your an athelete with intense physical activity a few times a week. The scale uses the bioimpedance and then calculates all of the results using the information that you provided which I believe is not that accurate. For example, I'm 5'11", 27, male however not all 5'11", 27 yr old males are the same, do you see the problem? So basically alot of their readings are CALCULATED based upon information that you give it, not true measurements of yourself. These are ASSUMPTIONS!! To test how unaccurate this weight scale is, I stepped on the scale, saying that I live a moderate life style of activity. The scale said my body fat% is 14.3%. I IMMEDIATELY set up the scale again, this time saying i live an atheletic life style and my body fat% is 9.7%????huh? Which one is it???? And why are they different, shouldn't my fat%, just like my weight be the same??? I mean nothing in my body has changed, just the setting on the scale. Also, all the results of the other features are skewered downward when I choose athlete mode, and vice versa when I choose normal mode. I personally think I'm in pretty decent shape, I don't work out like an athelete, but I do hit the gym, it's probably not "intense" but I do some excercising a few times a week. Quite frankly, I'm not sure if I should be using "athelete" or "moderate" mode, so I really just have no exact measurement of my body fat% or any other measurement(besides weight). I just know I'm somewhere between 9% and 14% which I coulda told you by looking in the dam mirror. This goes to show you that the scale is using the bioimpedance, but it estimates everything based upon factors. If you read the guide it states that some of the measurements are based upon studies. Like the BMR is based upon some famous study or something.... The scale has always measured my weight consistently. I'll get on the scale weigh myself and then get off and immediately weigh myself again and the weight is the same. HOWEVER, i've weighed myself a few times within a minute and I notice that the body fat%, muscle%, etc. are ALL DIFFERENT. The weight was always the same, but the body fat% was 1/2% off???? the time between weighings was about 10 seconds!!!! I kept doing this over and over and noticed that my body fat% could swing by as much as 1% +/-. More proof this thing is inaccurate. As this thing goes for over $100 I wouldn't recommend anyone getting it. Unless you really really want to monitor your progress. For example, if your on a diet, you could monitor your progress with this scale, just know that its not the most accurate thing and that the readings are really just BALLPARK. If I could do it all over again, I would buy a Tanita scale, but not this top of the line one, I would get the mid grade were you would still get the fat%, less some of the other features, like metabolic age....I mean who needs that??? And what would you do with it? And of course you would save some money. PROS: Accurate in reading body weight. Lots of features. CONS: fat%, muscle%, etc. are all based upon bioimpedance and assumptions according to the info you enter into the scale. So it's not truly accurate. Most of the features are really useless. BOTTOM LINE: Not worth the $100+ in my opinion. If fat% is important, your better off just getting a Tanita scale, but a mid-grade model that reads weight, fat% and muscle%. It's really all you need.
