Quite easy to setup.
I had a little trouble at first because I was pushing the buttons too hard. Called technical suppport and he told me about button pushng. Also offered an exchange if I couldn't get the scale to work.
In the manual: body fat, muscle mass, and water content were well explained but the one example of bone mineral content didn't fit my profile.
I'm going to look that up on the internet.
It has a lifetime warranty. WOW!
