Review on 💪 Xiaomi Mi Band 5 (Black): The Ultimate Fitness Tracker for Achieving Your Health Goals by Aaron Gordon

This is a HORRIBLE product. The description states that there is an SPO2 (blood oxygen) function and the Q&A confirms this. But there is no SPO2 function. The heart rate monitor shows a rate that is 40-50 beats lower than the actual rate measured by a separate device. The pedometer sporadically stops counting, sometimes leaving a gap of 500 steps. So just send it back. Right? No not at all. YOU PAY FOR RETURN TO CHINA. The post office charges $35 for return shipping. Other services are more. Buyer Warning. Revain would have you believe that returns are free, but you should read the returns information very carefully. A NOTICE. Please stop calling me. This review is an honest review and I don't want any "gifts" to change it.
