"I love the fact that keeps your initial weight and when you weight yourself again if it lights up in blue means its the same weight or less if it lights up in red it means you gain weight. Definitely I feel is for a one person use if you want to take advantage of this feature. It does not measure bmi only your weight. What I love about it is that you just stand on it and done , not like others where you have to touch first then stand. Turns off on its own. Edited: after a few days does not weight accurate it’s off on snd off."
