I had wanted this ring since it first came out but could never afford it. Now that you can use your FSA/HSA, it is possible. Since I used mine, I went with my favorite color rose gold. The color itself is gorgeous but not a true rose gold. It’s more of a true gold. Doesn’t matter because it’s beautiful and so functional. I look forward to waking up and checking my stats on the app. It is so accurate too! I thought I was getting a bit sick one day and it told me to take it easy so it picked up on the changes within my body. The sleep tracking is what I mainly got the ring for. I have trouble tossing and turning all night and this ring picks up on my sleep cycles. It will give suggestions of when you should go to sleep to get a better night’s rest. It is pretty comfortable to sleep with as well. Doesn’t bother me at all.Choosing the right size of ring is very important. Since our fingers do tend to swell in our sleep and with the weather. I recommend sizing up. I usually wear a size 8 but with the sizing kit, I found I had to size up to a 9. Even when my finger has swelled, it’s not uncomfortable at least for me.I have seen a lot of people being put off on the monthly subscription. Although it would be nice not to have to pay for one, I don’t mind it.As far as the work out option, I haven’t gotten a chance to test it. I do feel it needs better options to choose from with the workout options they have. If it were more like the options on my Apple Watch, it would make it even better. I also feel the period tracking could be better. It’s very basic. Just lets you choose a start date and your flow. This is what I wish Oura could put more effort into tweaking on the app. Its period predictability is pretty spot on. But why should we have to use a separate app if we want to get a more detailed breakdown of our menstrual cycle?I know there are other competitors with more reasonable pricing but Oura really is the way to go. I was able to easily put in my order here and got it the next day! Don’t order through the Oura site though. I had an order on their site that was taking forever to get any updates on my order and as it turns out, they were so backed up because they were busy fulfilling their Amazon contract. So just cancelled with them and ordered here and it worked out. If you’re debating on getting one, just do it! ### ⭐⭐⭐⭐⭐ Highly recommend *by L***U on June 19, 2025* I love this ring. I’ve only been having to charge it about once a week so the battery lasts. I’ve definitely dropped it a lot and nothing has stopped working so it’s fairly durable. It’s also waterproof and I’ve gone swimming with it multiple times without issue. It does get scratched easily if you don’t get the matte version but I feel like that’s to be expected of most jewelry like this. It’s very accurate in its data though and helpful in tracking sleep and monitoring heart rates. You do have to keep an oura subscription for it to work but it’s pretty cheap and worth the money. ### ⭐⭐⭐⭐⭐ Good item *by R***H on July 15, 2025* Wife absolutely loves this. It tracks her sleep and activities. Good battery life and quick to charge when she needs to. Fits well and nice design. ## Frequently Bought Together - Oura Ring Gen3 Heritage - Stealth - Size 12 - Smart Ring - Size First with Oura Ring Gen3 Sizing Kit - Sleep Tracking Wearable - Heart Rate - Fitness Tracker - 5-7 Days Battery Life - BandSmith Silicone Ring Cover Compatible with Oura Ring Protector, Elastic Case for Oura Ring Gen 4/3 Working Out - Patent Protected (Black+Transparent, M for 11/12/13) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/619253412-ring-gen3-heritage-stealth-size-12-smart-ring-size-first](https://www.desertcart.is/products/619253412-ring-gen3-heritage-stealth-size-12-smart-ring-size-first) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-06-18*
