I use it daily

Really great. It keeps you sane while dieting. Does not let a day of sudden gain break you down. Does not let a sudden loss create unrealistic expectations. It is like a good objective friend that teaches you to take your numbers realistically.
I really trust it. Even when the "true weight" seems totally crazy and offset, a few days later I always find out it has been very accurate in its predictions.
On top of that it works in us, European, british units and it is extremely easy to go from kgs to lbs to stones. A click of a finger will do.
Highly recommend.
