This is a Xiaomi Redmi 3 smart band. When I bought it, I was using an iPhone, but the connection with iOS wasn't very stable. I contacted Xiaomi, and they informed me that it doesn't work well with iPhones/iOS and is a product designed for Android devices. As a result, I haven't had a chance to use it, so I'm listing it for sale. I hope someone who needs it can make use of it. Regarding the appearance: - There are some signs of use and scratches around the edges. - There are light scratches on the screen surface. However, there are no particular problems with the overall operation. A charging cable will be included when shipped. Please also refer to the photos for the condition.
