I bought this scale in Jan. coinciding with a New Year's resolution for wt loss. It is attractive and worked well at first. All of a sudden, overnight, I gained 15 lbs. Had my husband step on and it was the same thing. So, for the price, 4 months of usage is not worth it. I am EXTREMELY disappointed and will be purchasing another scale - as you can imagine, nothing from Homedics. What a dud!
