Very light ring and it’s working
Review Image by Steve Lim Steve Lim
Review Image by Steve Lim Steve Lim
I like the looks of the ring. It is sleek and very light. Pairing it with the qring app is a breeze. So far, i tested all the functions and they work. Size 8 fits my index finger and i have small fingers. Good value for the money.

Won’t keep a charge. So it doesn’t work
Color: Silver Size: 11#
I loved this ring for like the first week maybe. It held a charge for three days and would charge really fast. Had great readings. Then it just stopped charging or doing anything. Really disappointed I liked this ring. Gonna have to get a better one I guess. Definitely returning this one.

Battery Dies soon
Color: Black Size: 11#
Worked well for about a month and a half. Now the battery only lasts 3 hours. Like the app and was all easy to use. But now I know it was a $40 bet I lost.

I really wanted this to work!
Color: Black Size: 10#
When this ring was working, it did great! The numbers closely mirrored my Galaxy Watch 4 Classic, which is pretty good! That was an expensive watch when it was new. One smaller issue was the app in their own manual didn't' work. I ended up having to get JRing from the App store. That was the only one that worked for me. The main issue I am having with it now is it will work for a few days, then the app stops reporting my sleep and heart rate. It kind of defeats the purpose of wearing it, really. The latest firmware update to the ring helped it to last longer, but it still eventually stopped working. If they get the firmware fixed up, I'd be happy to correct this review. It is a nice ring. I like the way it looks, and it worked well when it actually worked. At $40 it would be a steal compared to the other smart rings on the market! ... show more

App is very easy to use
Color: Gold Size: 10#
The app was very easy to set up and is easy to use. You can manually have it check your heart rate and blood oxygen level, as well as have it set to automatically check your heart rate at regular intervals. I have not used the sleep feature yet. It also automatically tracks your steps, minutes of activity and calories burned. You can set a daily step goal and choose to have it connect to the health app on your phone. Be careful when you measure your finger. I thought I measured correctly, but was a little larger on the size than I wanted, so I am wearing on a different finger. ... show more

So far even with all the troubleshooting I haven't been able to connect. So the ring is beautiful but worthless so far
