DO NOT BUY THIS SCALE
It was shortly out of warranty, and stopped working.  Nothing but an error message.  Customer service said it was an internal sensor, but they weren't willing to do anything other than offer me to buy a new scale for another $130!  I bought a $16 digital one on Amazon instead and it works perfectly.  I just track my own weight on another free app.  Don't waste your money.  Not worth it!
