Review on Feifuns Smart Watch: Blood Pressure & Blood Oxygen Fitness Tracker with Heart Rate Monitor - Large Full Touch Screen Pedometer Watch for Android & iOS - Men & Women by Jay Liu

I love just about everything about this fitness tracker. It looks good, works well, uses a very good app and is very cheap. I've tried many others and none were as good as this one. The only downsides I could find were that the display tends to blur outdoors in daylight and the bp measurements are inaccurate, but that's the case with almost all of these trackers. Otherwise, this tracker is a winner. To update. The tracker went from a winner to a complete loser due to a fatal error. Most of the functions still work, but the main function I bought this tracker for, the pedometer function, no longer works properly. Now it measures steps and distance incorrectly. When I complete a 2-mile measured lap, this tracker claims I've covered 4.5 miles. Not even remotely accurate and utterly useless as a tracker. Tried a second tracker to see if the first was faulty and it did the same. I am now not satisfied with this tracker.
