After using the Versa 4 for 3 weeks now, I've found it to be a huge let down. I've used a Samsung Watch in the past and found that much more reliable.
The Versa 4 is highly inaccurate on step counts, where every morning I wake up, it's saying I've done over 500 steps. The Fitbit app which you need is not user friendly, I found it's highly bloated with features you dont need. Next, you need to subscribe to Fitbit premium in order to get full functionality of the device.
If I had my time again, I would purchase the Samsung Watch instead
