Rating Fitbit Aria

For nearly five months since my wife and I use this scale without no complaints. We love its design and ease of use.
Once we faced the weight data and transcribe them into an Excel file. Today everything is done automatically. We can go see the results recorded on the Fit-bit website as our smartphone or our tablet. However to manage our operations we use the site "MyFitnessPal" that automatically includes the Fit-bit weight data of exercises and applications provided by "Runtastic".
It is a pity quun invited could not know his body fat percentage. No internet or without registration, the scale gives the weight. There is a difference in weight measurement with our old balance Terraillon (0.5kg to 0.8kg and more) without calibration, we can not say which gives the best value.
But in summary, we are very satisfied with the Fit Aria Bit-balance and we give it 5 stars.
