I've had better experience with the Body Cardio scale. Though I haven't validated against other measures, I believe the body fat percentage is accurate enough based on my subjective opinion (it has not been generous to me like another poster's experience). Research has determined that impedance can be +/- 4% from actual in optimal conditions and my scale seems to fall close enough within that range. Regardless, I use it for all the variables tracked. I look at body fat percentage but body weight is ultimately the value of concern. I don't agree $99 a year is a good value just for bf%, because I do agree that visual impression means more than a specific number. The subscription cost for Amazon's service may be a great value (privacy concerns aside) if their photo algorithm is within a couple points of DXA or hydrostatic.
