Purchased the item based on the glowing reviews. Nice big dial.Had no problem in zeroing it. But it is a HUGE scale!! Not ideal if space is limited.But the scale was clearly off by 5 pounds! Always showed upto 5 lbs less. Called Health o meter who advised me to try re-calibrating. That did not correct the problem.Returned it to Amazon immediately. Very dissapointed. Maybe I was just unlucky. (based on the other great reviews).
