Xiaomi may not officially have a U.S. presence, but its budget fitness trackers are a regular presence on Amazon and are understandably popular, given how much they offer for the price. The Smart Band 8 Pro is no exception. It may be double the cost of the regular Smart Band 8, but its still pretty cheap and that extra $50 nets you a much larger display, more sophisticated software, and, most importantly, a built-in GPS.
