Personally owned this, overall not bad and 3 months from now battery still good in shape.
However about the 16 profile where it can be auto detect once step on it, if you have similar attribute with different member, this "smart" scale couldn't differentiate properly.

About the display on the scale, it will be good if under low light condition, however if under bright sun you will barely see it .

pros :

• This version featured with 10 data points
• battery long lasting
• nice and simple design
• Non-expensive
• can keep track your health

Cons :

• Screen can barely see if under sun light
• can't detect profile if similar weight
