Review: So functional! - I’ve had the Oura ring for a month now and I love it so much! 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 desertcart contract. So just cancelled with them and ordered here and it worked out. If you’re debating on getting one, just do it! Review: Does everything I need it to and more! - I had an Apple Watch Series 8 for a while and I liked it but after wearing it for a while it would start to get uncomfortable and become a sensory problem for me. I have autism so I'm super picky about wearing things. Strangely it also started to leave burn marks on my arm. I still wanted be able to track my sleep because I'm a chaotic sleeper and have other important information about how my body is doing. I was a little apprehensive about the Oura at first because I can't even wear normal rings so I wasn't sure I'd be able to wear this one. Now I can say the only time I've taken it off in the last 6 months is when I need to charge it. It's so comfortable I forget it's there and my finger even feels weird when I take it off. There is a subscription fee for the app but I don't mind paying it. I was paying for multiple subscriptions for my Apple watch to get all the data I needed but this is just one small subscription. I do still wear my Apple Watch for workouts (and even during that short time it's started burning my skin) because Oura isn't the best at that but it is still the best I've found for sleep and general wellness. ## Features - SIZE BEFORE YOU BUY – Size with Gen3 Sizing Kit prior to purchasing Oura Ring Gen3 (different sizing from Oura Ring 4).
