Wyze watch 47 Accuracy

Watch 47 works but the event recording is inaccurate. The steps recorded do not reflect the actual steps. When comparing with a Fitbit the steps for a day will be several hundred steps less on the Wyze 47.
The heart rate shows the my heart rate goes to 40 bpm on most days. If my heart rate was that low I would be in more trouble than I am.
The watch is nice but it is not accurate.
