Used the Versa 2, Versa 3, now the Versa 4. First two versions were great. Really no complaints. This one on the other hand is not good. Many times no sleep data. Heart rate monitor is horrible. I will watch my heart rate and it will stay stuck at like 90 and never move. I will reboot the watch and then it will start to read. When exercising it will stop reading. I’ve been using this style for about 7 years, so I know how to wear the device. You would hope that it gets better as new ones come out, but this one is a failure. Will either go back to a Versa 3, or try a different brand.
