For starters, let me just say that I love this scale. It is, by far, the most comprehensive, fully-featured scale that I have ever owned.
While I like to monitor my weight, I've always believed that measuring body fat percentage is a better gauge of determining your health since weight doesn't consider muscle mass. This scale does just that, and so much more. Of course, like all body fat scales, you'll need to weigh yourself barefooted since it uses bioelectrical impedance to measure body fat, but this is common. (Note: if you have a pacemaker, you should NOT use this scale or any other with BI technology as it can cause your pacemaker to malfunction.)
Beyond weight and body fat measurements, this scale does it all and then some. It also measures heartrate, air quality and it even tells you what the weather will look like for the day. What's particularly amazing is that the scale will automatically identify up to 10 people when they step on it by remembering prior measurements. This is incredibly convenient.
The scale also comes with a companion app for iOS (but I don't think one is available for Android) that works great to monitor your health long-term, and the app also syncs with HealthKit, MyFitnessPal and many more apps, which makes it super simple to streamline into any lifestyle where monitoring your health is important to you.
Like any scale, I can't really say how 'accurate' the weight and body fat measurements are since I don't have a calibration weight, but I can testify to the scales consistency. The scale is EXTREMELY consistent.
I only have two small complaints with the scale. First and foremost, the scale comes with optional feet for which to use in carpeted situations, but the scale simply is not accurate on carpet--like most scales. Secondly, the scale is very expensive. It was $30 more expensive than any other scale in the store but I bought it based on the glowing recommendations, and after owning it for a while, I'm glad I did. That being said, I still think the scale is a bit overpriced, but if you're willing to pay the premium for features and reliability, I don't think you'll be disappointed.
