I balance for several months now. its design is superb. it is very easy to start and to use, and extremely reliable even there: actually no problem. It was settupé for those of the family. we connect across PCs / IE, ipad, android to see the curves. Sometimes it happens that she does not know to whom attriber a weight (when 2 people are close), but we can settle the case by reallocating measures since PCs / devices.
It is interesting to make stats and testing, as it is very accurate; weigh just before and after 1h of such race. From that side it is very informative. The data also connect to Endomondo I use elsewhere and ca allows for a comprehensive follow-up, almost automatically, to do anything. And here we can see the correlation between efforts and results.
I like the attention data concepts; it has regular prompts warning to watch out for measures (such as ca actually can naturally vary +/- 2 kg a day) and how we reacted. In fact it is more a tool to follow up on for months to the day, we quickly see that makes no sense.
So I'm very happy with this product; class design, top functionality, reliable, and useful and relevant results.
