Review on 🌈 feifuns Smart Watch: Advanced Health Monitoring Fitness Tracker for Men and Women – Heart Rate, Blood Pressure, Oxygen, Sleep, and Activity Tracker by Richard Nonya

Good - step tracking, sleep tracking and daily heart rate worked well and seemed reasonably accurate. I only had to charge it once a week. It's okay - the phone app is a little clunky, the phrases are weird but understandable. The initial setup required me to enter all of my physical information (height and weight) in metric units. The ability to use US Customary units was not available prior to the initial setup. Sleep data wasn't available immediately in the morning of each day, but surfaced sometime before noon. Evil is unreliable. The watch has been factory reset twice, but first I blamed sweaty work gloves that randomly activated the touch area on the screen. Both times the user's wallpaper and all history for the past week was lost. On October 3, the screen became difficult to read with blurry vertical stripes and horizontal grid lines. Revain's return window closed on September 29th, otherwise I would have returned it.
