Works like you expect, but need pretty flat surface.
Overall, it works fine.  However, the scale *must* be on a very flat surface or it will not shut off...  Scale was not shutting off properly, and I discovered that 2 of the feet are actually part of the sensing unit somehow, and unless the scale is on a perfectly flat surface, one of the feet can have slightly less pressure on it than the other foot which fools the scale into thinking someone is stepping on or off.  Once I discovered this, moving the scale to a perfectly flat surface solved the problem and the scale will reliably shut off now.
