Review on NOERDEN Hybrid Smartwatch MATE2+: Unisex Water-Resistant Smart Watch with Connected Movement, 40mm Case, Long Battery Life - Tracks Physical Activity - Mobile App - Khaki by Russ Mashlan

The watch itself is great. The service is very good because I contacted them and twice I got an answer but no solution. I've been a marathon runner for over 25 years, know my body and use a Polar Watch, Garmin Watch, Apple Watch and now a NOERDEN Watch to track my activity, pace, heart rate, calories etc. Apple Watch Series 6 with my iPhone 12 mini in the latest ios version. That's the problem: while the Appale watch reports 1039 activities in a 234-minute (3:54) hike, the NOERDEN watch reports 103.8 calories in the same time. See attached pictures. Still waiting for a decision and considering returning the watch.
