JSRing 4+

The device only records sleep overnight. If you work nights this function is useless.
Day 2 of using the device and it disconnecte. I haven't been able to get it to connect. When not connected you have no access to historical data.
It doesn't integrate with any of my health apps, preventing this data from being preserved elsewhere.
Recommend the app get updated to allow presentation of the data when the device is offline. Integrate it with other health apps and work on reliability for the hardware.
I'll be returning this.

I’ve had my smart ring for a week now. Once I figured out how to charge it and set to the app it functions perfectly. I’m much more confident in working it into my life style. I am a caregiver constantly washing my hands so that activity is still being worked out. The Ring does everything I need especially helping track sleep habits and daily steps. The price is reasonable compared to better known brands and I think mine looks like a nice piece of jewelry. The big test is longevity. No complaints going forward, thanks!!

The ring itself looks very nice. However, when I first got it, there was a couple of issues that needed to be fixed so I got a hold of the people that sold it and they were very helpful and we got the issues taken care of. Impress me more than anything was as soon as I sent an email. I always got a reply within a couple hours. I would definitely buy again from those company………
