Review: my yellow gold Gen 2 ringconn is pretty, accurate, & anti-scratch! - Everything from its pretty aesthetics to its battery life to its functionality & accuracy is PHENOMENAL! It’s so slim & sleek (noticeably less bulky compared to the Oura Ring!) And it blends in with my other yellow gold jewelry! In over 6 mths the yellow gold color hasn’t tarnished or scratched off (like customer reviews say the oura ring does!) It truly IS waterproof! I never take it off when washing my hands or washing dishes & it still works great! I’m so impressed with how accurately it detects my sleep patterns, & it knows if I fell back asleep or took a nap! It also has everything I need for tracking my cycle (you can input notes & symptoms etc). I really purchased this ring because I wanted the BBT feature to track my ovulation, but it only reads your SKIN temp so it’s not as accurate as I’d hoped… Helpful “Find My” Feature: I misplaced my ring in the house the other day so I used the app to find it by sounding a beeping alert & lighting up/glowing blue! And the map on the app accurately showed exactly where in the house my ring was! It is so precise! The battery life is VERY LONG (8+ days!), and the charging time is SUPER QUICK! (like under 45 min!) And you don’t need to pay extra $ for the APP (unlike other competitors!) which is a big plus! Overall I am SO impressed with this fitness ring and I highly recommend! UPDATE: My mother in law wanted the silver GEN 2 ‘AIR’ for her birthday & she loves it so far! (see the pic of it on her pointer finger. It looks great on the same hand as her white gold wedding band!)
Review: Useful data that is reliable up to a point - My sense is that with RingCon versus the alternative that requires paying a monthly fee for service, is that RingCon is more than good enough to avoid paying a monthly fee. That said with all of the ring based solutions they are best used for everything except exercise. For that you really want something that fits as a band on your wrist to obtain accurate exercise data. But if you are looking for sleep data then RingCon certainly works very good for this purpose. Monitoring through the day also is good though if you are constantly having to remove the ring because of something you are doing with your hands, perhaps this might not be the best solution. One fear based upon reading on the Internet is battery longevity. The Internet suggests that the ring's battery will loose the ability to hold a charge in a year's time. Likely this could be because of the very small battery embedded in the ring is worked hard and over a year time gives up. The battery is not replaceable given it is encased in epoxy that seals the ring such that you can wash with the ring on. Apparently there is a trade in option and I believe the cost is $100. Which suggests that the long term cost of using the ring is not a usage fee, but $10/month given the battery wears out. Likely the competition isn't saying this such that their cost of operation is their monthly fee plus whatever it costs to replace their ring in a year or so... Would I buy this again? I want to say no. I found that after a month I learned all I needed from the data and the data wasn't changing. In the end it cost me the price of the ring to learn to solve why I wasn't getting a good night's sleep. Though it could be said that the ring's cost was cheap if that is the case.

## Features

- [Size Before You Buy] Before purchasing the RingConn Smart Ring, we highly recommend acquiring the RingConn Sizing Kit to determine the most comfortable and suitable size for your finger. Please note that the RingConn Sizing Kit is only compatible with the RingConn Smart Ring
- [Not Standard Sizing] RingConn Smart Ring differs from standard rings as it contains sensors on the inside. Therefore, we recommend using the RingConn Sizing Kit to determine the best fit. The RingConn Smart Ring is available in sizes 6 to 14, accommodating various finger sizes
- [How to Measure & Fit Check] Wear the sizing gauge snugly around the base of your finger, ensuring it doesn’t rotate freely. We recommend wearing it for over 24 hours to determine your most accurate fit. For optimal data and comfort, the RingConn Smart Ring should fit snugly against your skin without rotating. When testing for the best size, make sure the sizing gauge remains tight around the base of your finger
- [Choose a Finger] The RingConn Smart Ring can be worn on any finger and on either hand. For optimal accuracy and comfort, we recommend wearing the RingConn Smart Ring on your index, middle, or ring finger. Be sure to size the exact finger on which you plan to wear your RingConn Smart Ring for the best fit
- [Manufacturing Quality] RingConn Sizing Kit is made from premium-grade plastic, while the RingConn Smart Ring is crafted from aerospace-grade titanium, coated with a scratch-resistant layer for outstanding corrosion resistance and durability

*by N***N on June 21, 2026*

I’ve been very impressed with my Gold RingConn Gen 2.
