Prefer over Oura Ring 4
Brought this after returning the Oura ring ceramic, fit is so much more sleek and stylish. Iโve been wearing it now for over 6 weeks and itโs like a part of me I donโt feel it- at first it felt alien so donโt worry the feeling goes away. The charge lasts 8-9 days normally - absolutely brilliant - charges quickly as well within maybe 1.5 hrs from dead to fully charged. The sleep detection is this rings super power - does a fantastic job. One thing I found is I started wearing it on my non dominant hand as it was registering steps just from hand gestures, but once I swapped it on the non dominant hand that stopped. It does learn your movement over time. Now Iโve done that itโs super accurate- Iโve compared my steps to my Apple Watch that I wear during the day and itโs pretty much spot on. It is very durable but Iโve scratched mine washing pots and pans so metal on metal is a no go. Connects super easily to the FREE app, the app also has some great features for tracking your health. Overall Iโm super pleased and I think for the money itโs worth trying if your looking to be extra aware like me.

The Best Subscription-Free Smart Ring! Super Thin and Comfortable
Iโve been wearing the RingConn Gen 2 Air for a couple of weeks now, and it has completely exceeded my expectations. If you are looking for a high-end health tracker but hate the idea of a monthly subscription (like Oura) or a bulky smartwatch, this is the one to get. โWhy I love it: โInsane Battery Life: Iโm getting a solid 10 days on a single charge. Itโs amazing to go over a week without even thinking about the charger. โUltra-Thin & Light: At only 2mm thick and weighing next to nothing, I genuinely forget Iโm wearing it. Itโs much more comfortable for sleep tracking than any watch Iโve owned. โNo Subscription Fees: This was the dealbreaker for me. You buy the ring, and you own all your data. The app is incredibly detailed and doesn't hide your insights behind a paywall. โComprehensive Tracking: The AI-powered insights for sleep, heart rate, stress, and SpO2 (blood oxygen) feel very accurate. I especially love the "Sleep Insights" which help me understand my recovery. โDurable & Waterproof: Iโve worn it in the shower and while swimming with no issues (IP68 rated). The stainless steel finish is also holding up great against scratches. โHelpful Tips for Buyers: โGet the Sizing Kit First: Smart ring sizes don't always match standard jewelry sizes. Use the RingConn sizing kit and wear the plastic ring for 24 hours to ensure a perfect fit (fingers swell at night!). โCharging: It comes with a sleek magnetic charging dock. It doesn't have the "charging case" of the standard Gen 2, but since the battery lasts 10 days, the dock is perfectly fine for home use. โApp Syncing: It syncs perfectly with both Apple Health and Google Fit, which is great if you want to keep all your health data in one place. โBottom Line: If you want a premium, ultra-thin smart ring that tracks everything accurately without charging you a monthly fee, the Gen 2 Air is the winner. Highly recommended!

Excellent smart ring
I am loving this smart ring. I ordered it in galaxy gold, even though I am not a fan of gold, as it looked more bronze in the picture. In reality itโs almost copper, which I absolutely love. Aesthetics aside, I am very pleased with the information I get from it. Itโs really useful and Iโm very pleased with my purchase.

Lovely ring, battery life is questionable..
Absolutely love the look of this ring, I ordered the dune gold and the colour is so pretty! The ring itself is not bulky at all and looks very sleek! (way nicer on the eye in comparison to an Oura Ring) The app is brilliant, great features and super easy to use! However my only negative with this ring is the battery life! I believe itโs advertised to last 10-12 days, whereas mine only lasts 6-7 days? Although this is still a decent amount of time, I would have liked to have got what was advertised! I am unsure whether Iโve received a faulty one as I seem to be the only one with this issue! I have had this ring for 2 weeks and it will need to be charged a 3rd time in 2 daysโฆ I will most likely have to return and see if I can get a replacement. Itโs a shame as I do really love this ring other than that!

Battery life deteriorates after 4-6 months
This was initially such a great buy, a cheaper version of the Oura ring. However, the battery started deteriorating after 6 months. It wouldnโt hold charge as long as it used to, so I wouldnโt recommend. The new Oura ring 5 is lighter and thinner than this, despite the subscription you have to pay, I do think it is better than this one.

So far so good!
2 days and so far so good! It's very accurate and easy to wear. I got a size 8 which I wear in my thumb, it doesn't look to big and I researched a lot to find the thinnest type without subscription!

Great, but doesnโt last.
I initially had a really good experience with this ring and would have gladly recommended it. However, Iโve had the ring for a little over a year now and the accuracy and quality deteriorated very fast and the battery life has become completely unreliable. Iโve had to charge the ring multiple times a day now and the ring dies while Iโm sleeping so the tracking is completely off. Iโve reached out to customer support as I assume there is some fault with the ring.

Loveit
Love my Ringconn! It does everything the oura does for half the price and no monthly subscription fee. Itโs also sleeker and less bulky which is something I prefer. The app is awesome and easy to use it has different sections for stress, sleep, vital signs, activity, exercise and cycle tracking. The dune gold colour is super cute itโs like a darker rose gold/bronze colour which is beautiful. 10/10 would recommend

Happy
Love this ring. So far it works great and is so comfortable to wear. One thing Iโve noticed is that the steps are way off sometimes. But I do understand that it could be hard to track as every hand movement could indicate a step without having GPS tracking. Getting 10 days out of a charge so far. The finish in Dune Gold is beautiful. So far so good! Update: It has been almost a year and I still love my ring. It had a slight battery issue and I let the company know as I was giving feedback and they replaced the ring with a new one no problem! Great customer service since I wasnโt even asking for a new ring, just letting them know, and they did it anyway. Love RingConn! Will continue with RingConn

Pretty good product
Product works great and is helpful and pretty accurate in my measurements. Customer service is also really good. I had faced an minor issue over a year after getting my product and over the warranty period and had gotten a free replacement after the regular fixing efforts didnโt work from my end.
