i dunno. i have on in my bathroom that i rarely step on because it's always several pounds over what i weight. when i do step on it, i just look to see if i'm further down the dial than last time, as opposed to looking at what number it ended up on.
the funny thing is when i have company over and a female goes to use my bathroom. it's almost guaranteed that she'll come out of there freaking out about the scale. no one can seem to resist stepping on a scale in an unfamiliar bathroom. it's like peeking in the medicine cabinet. you never hear dudes coming out of the bathroom complaining about the scale making them feel fat.
