It is a very fine gadget! It was a question that I always ask me: how many steps I can do in a day and now I have the answer.
very simple to use, the stastic are good.
I did find no problem in the installation and in the use.
it is possible to export data in csv.
I am not sure, but I have the impression that the battery consumption is higher from when I use it and I have to charge it before the end of the day.
