No calibration option, requires two weighings
Seems to work just fine. I'm used to scales that you step on to activate and zero out, then step again to weigh yourself. This scale seems to just want you to step on it.  I've learned that I need to do two readings, since the first reading is always about two pounds more than the second. Other than that, it's attractive, and the blue light means I can weigh myself in the dark.
