Query: Worse off than no scale at all!

The whole point of having a scale is pretty simple; you get on it, and it accurately tells you your weight. This product does not do that. It gives highly fluctuating readings such that one never knows their actual weight. It is advertised to be accurate within .2 lbs. No way on earth is that correct! You'd expect a digital scale with these features to be more accurate than a mechanical scale, but that is just not the case. This is an awful product. Do not buy it! Either go with a good mechanical scale that will be consistent, or invest in a reliable scale. I bought this thing and have no idea what I weigh. Awful...just awful.
