Title: Don't buy it!
Review: This review is for the HBF-400. I returned mine as defective. I stepped on it 5 times in a row and got different weight readings. Depending upon where you put your feet when you get on it, you get a different weight. I could move my toe 1/2" and the reading would be different. The bodyfat reading was way off too. About 5% to high. Hopefully mine was defective and the others aren't like it. I wouldn't recommend buying one though since mine was so bad.
Is the review positive or negative?
