Ozeri Gen II Digital Bath Scale w/ with Body Weight, Fat, Hydration and Auto Recognition $21

These type of scales are not too accurate on every feature except weight.The most sought after feature, body fat percentage, has a wide margin of error. There are two things wrong with it. One, the technology that it utilizes, bioelectrical impedance analysis, is in itself inaccurate and not considered an official reference method. Commercial products such as this one also tend to scale the percentages down from the actual body fat percentage reading. Two, the BIA conducted from these scales only measure the bottom half of an individual's body. It is required that two node placements, one on the foot and one on the hand, are used to accurately test the impedance of fat tissue throughout the whole body when using BIA.

With all that being said, I would recommend this mainly for it being a relatively cheap digital weight scale. If you do choose to use the other features, stick only to the body fat percentage feature. Although it is not entirely accurate, it is more reliable than the other features. And if you do use the body fat percentage feature, it is only a good feature to use as a measurement of progress over time and not as a measurement of your actual body fat percentage.
