A very affordable sizing kit to determine your size before buying an actual smart ring. This was a dollar and I feel like it works just as good as a $10 kit from the actual RingConn store.

I have had my RingConn Gen 2 Air for a month now and I absolutely love it. I ordered the sizing kit prior to placing my order for the actual ring. Sizing kit rings are true to size. Honestly, the ring looks and feels high quality. I am able to wear my ring 24/7 no complaints. The battery lasts about 9 days and the data is fairly accurate! Connecting to my phone is very easy. The ring gives you great feedback on your data and sends your phone reminders if you are stationary for too long or if there is an abnormality noticed. So far 10/10! I recommend it to my friends and family. Only thing to note is the ring can scratch. If you take care of the ring, the scratches are minimal.

I’ve had this for 1/2 a day and I really like it. We will see how it/the charger holds up as I’ve seen some people say it doesn’t last as long as it should. It was so easy to set up and had like 75% battery, then only took maybe 15 mins to fully charge. App is easy to navigate and frankly looks good. I did a small work out and it’s accurate with the steps so far. My mini stepper counts as well so I compared to that. All other vital signs seem to be in line with what my normal is too. It’s comfortable, not heavy or thick. But still feels high quality, I was pleased pulling it out of the package. UPDATE: It’s been over a week and I still like it. The battery would’ve lasted just about 9 days, I charged it before it got to ~0%. Good enough for me. It charged quickly too, did some chores and it was done. I keep seeing reviews with the app being troublesome but I haven’t had any issues and I rather enjoy it. There’s a lot of information. I saw an update for it so maybe that’s the issue??? The ring has been really comfortable, I did get the sizing kit and it’s worth waiting the extra day or two. I also see people complaining about the size when this company and other smart ring companies clearly state they don’t follow regular jewelry sizing. So truly size before you buy unless you’ve owned one before. Stats are overall pretty accurate. I somewhat know what time I wake up randomly while sleeping and it does match with what the app says so I tend to believe the rest of it for sleep. I’ve counted off steps in my head and then looked at the app — if I walked 50 steps it logged 50 steps. All of my workouts have been detected, time/calories/steps, all there. Update #2: It’s been 3 months now 1/10/26 and I still love it. I even got my mom to trade her Fitbit for one and she loves it. Maybe I got lucky but I haven’t really noticed a difference in my battery levels, even with the ring tracking more and more things 24/7. The only thing I do is not let it get to 0% it’s not really great for any battery to my knowledge. I’ve done multiple updates for the ring and app, no issues. I’ve only enjoyed the new features. Tracking still works, workouts are still detected and everything. Also, I hardly take it off and it’s less scratched than I thought honestly, and I’m not careful. Overall, still 5 stars, still happy I ordered, still loving it.
