Does what I expected, nice appearance and with a lot of choice of formatting screen.

This is what I've been looking for. Long battery life, 11 days. You can set it to airplane mode so you're not always exposed to radiation. And when you turn airplane mode off, it's instantly connected to your smartphone. It has just as many features as any other smartphone. The strap is so soft and flexible that you don't even feel it around your arm. I bought one for my mother in white too. It was also very nice. My mother is 80 years old and still very active, and she's very happy with it. Easy to use for her.

I don't like it, luckily I can still tell the time. A pedometer registers if you even move your arm, which isn't considered a step.
