Positives
The bracelet is extremely discreet wrist, even for a woman. And for me that does not like to wear a watch, I totally supported.
When the battery starts to weaken, if the bracelet is regularly synchronized, it receives an e-mail to inform us that we must think about recharging. It also receives by e-mail a summary of his week, and his badges.
There is an android application and is compatible with other android applications that can use its data for further monitoring.
The vibration which announces that the goal has been met is a true feeling of victory, to look forward to!
The functionality to a food monitoring, via an application, seems very tedious, and the method simple calorie counting is not effective anyway. Personalized dietary advice would have a lot more interest. Even provide menus according to profiles and activity type.
Negative points
The small lights display rather than an exact account of not quickly becomes annoying. One wonders if one is ever quite early in his step goal or rather towards the end, and if we must still make a 1-minute walk or 30 minutes ...
The bracelet is complicated to, I have to dredge up every several minutes to get to the re-threading. What happens to me at least once a day because I did not want to take the chance to test it in the shower.
To enter sleep mode, you must tap the bracelet, I happened frequently, especially when I push the stroller with my daughter on a road a bit bumpy as the function is triggered alone putting me to sleep mode in the middle of the street.
The silent alarm is just that, a silent alarm, it does not take into account the analysis of your sleep to wake you "at the right time" to a specific time as do other revivals. I personally think having wireless technologies as bracelet or phone near the bed can disrupt sleep, so anyway, I do not wear it at night.
Unlike other bands, this one is not able to estimate the number of stair steps covered, this removes an incentive to take the stairs instead of the elevator.
When you make a special effort, cycling, running or otherwise, you must yourself note down the start time and end time, via a PC or your smartphone, it is a manipulation that takes a little time and quickly becomes tiring. It lacks a little button on the bracelet that would make a point marking the start and end of an activity, to be more then just enter at the end of the day what the activity s' is.
There is no battery status tracking on the bracelet itself, if one forgets to synchronize to see his state, one will be surprised to see him off in the middle of the day.
I guess the function to be with his challenger friend (s) is interesting but does not know if anyone else has a Fitbit, it is useless.
Conclusion
The tool has achieved the desired objective, allow me to understand what the habits needed to make the 10,000 no recommended activities. Once taken habits, we get tired of seeing a similar graph day by day, and lose interest in this bracelet that we end up putting in the closet ...
