Skip this unless you want a scale that looks nice but doesn't work.
It looks nice, reasonably priced ($20), but is completely worthless for what it's for. Most of the time it fails to measure your weight (returns with the result of ERR). I find that standing completely still for about 7 seconds (approximately the amount of time it takes to give you a reading) helps avoid the dreaded ERR result. Unfortunately, when it does return something, it returns measurements that can vary by as much as 2 pounds for the same person. Maybe I have a defective product or just expecting too much for a $20 scale? YMMV.
