Bests & Worsts Reviews from Amazon

It doesn’t work! I calibrated it then got on the scale and it said I was at least 30lbs less than what gym scale and the doctors scale says. As much as i wish I was that light I know I’m not. Every time I step on the scale I get a different weight. And by different I mean 10lbs heavier or lighter within minutes of each other. It makes no sense. I am very dissapppinted
