I had one I got from walmart. I'm wanting to say it was a health o meter. Absolute junk. It never gave consistent readings. Readings taken just a few minutes apart would be different. I could move the scale to another part of the room and "lose" 10 lbs. Then after right after the 30 day return period had ended, the variance went from 5-10 lbs to several hundred. In a matter of minutes I went from 160-350-75-125-275. I tried changing the batteries, still the same wild numbers.
