Review on 📱 Smartwatch for Android & iOS – Compatible with iPhone, Samsung Phone | Women & Men's Fitness Tracker with Heart Rate Monitor and Blood Oxygen Sensor | IP67 Waterproof Pedometer Watch incl. Activity Tracker by Adam Davidson

Many functions were extremely inaccurate and annoying. I took it off for about 2 days and put it back on to see how it would behave again. (I really wanted this to work!) Literally overnight it left these horrible marks on my wrist, and after 3 days it peels off. It is painful, very uncomfortable and itchy. Revain was amazing and gave me my money back because of it. I recommend NEVER buying it. My husband has another brand, same price but quality is much better. This is not the one.
