RingConnRingConn Gen 2 Air Sizing Kit - Size First Before You Buy - Choose from 9 Sizes - Sizes 6 to 14 - Only Smart Ring

I was really excited to try the RingConn Gen 2 smart ring, and overall, it made a great first impression. The sizing kit was spot-on. I found my ideal size quickly, and the ring fit comfortably throughout the day and night. The sleek design felt unobtrusive, and I often forgot I was even wearing it. One of the standout features for me was the sleep tracking. It consistently matched how I felt in the morning, accurately reflecting my sleep stages and duration with helpful insights that felt genuinely useful.Where the RingConn Gen 2 started to fall short was in activity tracking. Step counting was inconsistent compared to my smartwatch, and the calorie burn estimates seemed off, even on more active days. I also noticed that the heart rate monitor and blood oxygen readings were not reliable during exercise. The readings would lag or spike inaccurately, making it difficult to trust the data during workouts, which was a letdown since I had hoped to use it as a low-profile fitness companion.In the end, as much as I appreciated the form factor and sleep tracking capabilities, I decided to return the ring. The drawbacks in activity tracking, heart rate accuracy during exercise, and unreliable O2 readings made it hard to justify keeping it for my needs. It’s a great product in many ways, but it just didn’t hit all the marks I was looking for.

Honesty hour: this is the first smart tech product I have purchased. With that being said, I was uninterested in a product that would waste my money, not do as it says, and ultimately be a purchase that sits in my jewelry box garnering regret. I am here to say: this ring is not that.I was lovingly influenced by a coworker to delve into this world, specifically the Ring Conn Gen 2 Air, when I was shopping for an Oura Ring or watch. I came to find out that this product is an incredible value for its price. I highlight recommend trying it out for yourself with the sizing kit and seeing how you like the fit (the sensors are a learning curve) and the placement (pointer or middle finger of your non-dominant hand)It was super easy to connect to the app, with no secondary purchases required. In the two weeks I have had this product, the insights it has offered me have been helpful, and accurate. I can’t speak to the comparison of this data with other smart tech, but the fitness features, the stress insights, the sleep tracking and more have proved very helpful.My only feedback, and I’m sure it will come in new updates, is certain features in the period tracking feel missing. For my friends trying to plan pregnancy, I would do some more research into how this could help and what features may be in incoming.Also, for what it’s worth, the ring is stunning and without me talking about it to friends, I’m not sure they would notice it was smart tech and would just assume it was a ring!

I previously ordered the ring on the manufacturers website and after over a month of waiting I decided to cancel my order and go through Amazon instead for the 2 day shipping. I’ve had my ring almost 3 months now and love it. I actually love it so much I have fully stopped wearing my smart watch. The setup was so easy. The color is so pretty. This ring is insanely accurate- it tells me I’m sick before I come down with any symptoms. I love the cycle tracking feature as well. It’s also a major plus that I can go well over a week without charging. I highly recommend.

Disclosure: This is my first smart ring. I am a triathlete. I have had other Fitbits and $500+ Garmin watches that track my sleep and daily activities and exercises. Therefore, this review I will be somewhat comparing with the Fitbit and Garmin devices.I have done lots of research on smart rings before buying this one. I like the style of it that I can wear it as a promise ring for my fiancé. The best thing is that it is subscription-free. Fit: I bought the RingConn’s ring kit to try first. I aim to wear it on my left ring finger and I was between a size 8 and 9. It was a tough choice but I went with size 8 (after returning the size 9 because it was too loose). In the colder days I can remove the ring with some twisting and turning. But in warmer days, my finger swells, so I usually rinse my hand under cold water, apply some body wash/soap, and it can easily be removed. If I had gone for size 9, it would have been loose for me. Also, don’t trust the sizing kit completely. I had to return the real ring size 9 even though the sample ring size 9 fitted me great. I ended up with size 8.Form: I like it that the diameter is not too wide. It looks like a wedding band but slightly wider. I got the silver one and it looks great.Heart rate monitoring: the ring takes your HR once every 5 minutes. It gives you a HR range for that 5 minute (e.g. 51~55 bps).SpO2: it takes it once every 30 minutes. It gives you a range (e.g. 95~96%).Heart rate variability (HRV): it takes every 30min. It gives you a wide range (e.g. 30~50ms).Skin temperature: looks okay to me. It gives me a temp every night.Respiratory rate (bpm): it just gives you an average range without a graph to deep dive.All-day stress index: it gives you a number every 30 minutes, for the entire day. It gives you a score throughout the day.Sleep: (1) the total time asleep for the past 7 days has been slightly off. The ring is about 50/50 chance it knows when I start sleeping. Waking up seems accurate though. (2) The sleep stages: it gives me how many minute I was awake, in REM, having light sleep, and in deep sleep. I can’t say the accuracy of it but comparing to my garmin and fitbit, the range is a bit off. Garmin says I have 3hr8m of REM while RingConn says I have 1hr42m. Garmin says I had 1hr1m Deep sleep while RingConnsays I had 1hr55m. Garmin says I had 4h23m Light sleep while RingConn says I had 4h48m. And Garmin says I was awake for 3min while RingConn says 5min.Steps: it tracks steps pretty accurately. Compared to my Garmin, out of 10k steps, the difference is maybe 200-400 steps. Same goes with running.Sports: the steps and heart rate actually pretty decent for running. If you are more into accurate with heart rate during exercising, go with Garmin heart rate straps. For cycling, forget about it; the ring tracks the heart rate very poorly and it doesn’t track steps because you are cycling. I don’t even want to try pool swimming. Overall, I will most likely continue to wear it daily. The app has lots of data and graph to go through. For the price, I am not expecting it to be as good as garmin but I think it does a great job with room to improve. I have showered with it, hand wash with it, and I accidentally dropped it from my waist level. It is still working fine. The battery does run for at least 7 days and more with one charge. I didn’t need the sleep apnea detection. As mentioned, they have room to improve. Don’t expect it will do everything perfectly. That’s why this is the Gen 2.
