I already had this balance for 5 years and that gave me satisfaction. And always with the same set of 4 AA batteries. But misuse made him give up the ghost. Yet the record is clear: do not use the feet or too wet body. I left the hammam, dripping, and without thinking, I've used. It was his last beep! That's why I bought exactly the same that Amazon still offers. The scale stores the weight you deniers, fat content, water, muscle mass and shape gives clues and obesity for 4 different users. Simply enter the size, age and profile are (sports or standard). Commissioned Monday received Thursday. Nothing to say about the Amazon service. I just wish that the balance is put into an additional cardboard. The original packaging is canceled as is. But, good, everything arrived in perfect condition. For your information, I have handed over the balance of my old batteries that are not worn and that, after 5 years of daily use.
