Currently unable to comment on the product, as it WILL NOT WORK WITH MY PHONE. Apparently iPhone 8+ is "too old" but this information is buried at the end of several paragraphs. Such a crucial piece of information should be displayed PROMINENTLY in the product description. The series 9 version of this watch was designed to work with the latest software of phones and cannot be set up without one. It may work with "updated" Android phones, but I have no idea which ones. Check the fine print before you buy!
