This balance perfectly meets my needs, I expected no less. Previous reviews scared me when I wanted to order but in fact I do not see what does not work because everything goes perfectly in my case. The installation and synchronization with the application LIBRA is very well done and just 3 minutes. In the morning I turn on my iPhone and I put bluetooth and I barely have time to go to the toilet that the balance has already recognized the iPhone. No, frankly, there is no reason that it does not. The weighing is fast also. The only downside I found was that, being 5 to use balance, it does not always recognize the person weighs. Anyway, just click on your name on the application and it just happens to be ... So it's not a problem. However, it is supposed to recognize people. This should get better with time. I suggest strongly that balance if you please!
