Fantastic Product
Love it. Use it every day. Setup was quick and easy and it syncs effortlessly. My wife and daughter have similar weights and builds and sometimes it is unsure who the user is, but the conflict resolution is pretty intuitive, especially after the first time. The only trouble I had was after I took it out of town and had to connect it to a different network, I had trouble getting it re-connected to my home network.  Switching from the app-based setup to the web-based setting straightened that out for me with little trouble. That's the only thing keeping me from giving it 5 stars.
