Within the 6 months of having this ring I’ve noticed that scratches have only really appeared where I hit my finger against my computer mouse at work. The rest of the ring looks great! I have some sleep and health issues so this tracking has immensely helped me find out what I need to adjust. Based on your sleep score, temperature, and heart rate, the app will let you know if something is going on - especially illnesses. It’ll let you know something minor is straining your body when you are going to be sick the following day, then show major signs when you’re actually sick, which gives great peace of mind. I also started a new medication and my general scores lately, along with other factors, have shown that I need to revisit this medication choice. I’ve also really enjoyed the cycle tracking while being off of birth control, this along with ovulation testing has been the best hormone free birth control. This has been the most accurate tracking and prediction I’ve had, in comparison to Flo and Stardust. These rings are amazing if you’re looking to have some motivation for activity, cycle tracking, sleep monitoring, and general peace of mind.

The Oura Ring 4 sizing kit was really helpful in finding my perfect fit before ordering the actual ring. The different sample sizes made it easy to test comfort for a few days. I liked that it’s lightweight and gives a good idea of how the real ring will feel. The only downside is that the samples are plain and not the real material, so it’s hard to tell exactly how it’ll look—but overall, super useful and worth trying before buying!

If you’re planning to buy the Oura Ring 4, this sizing kit is almost essential. Here’s my straight-talk review: What I liked: The sizing kit gives you multiple trial rings (sizes 4-15) to test your finger and fit. Best Buy +2 Android Authority +2 It helps you understand that Oura’s ring sizing doesn't match standard ring sizes — many users found they needed a different size than their usual jewelry ring. The fit matters a lot: the company says a proper fit leads to better comfort and data accuracy. You typically receive a credit toward your actual ring purchase, so the sizing kit effectively reduces risk. One small caveat: The sizing rings are made of plastic and feel different than the actual titanium ring. Some people notice differences in how the plastic kit fits versus the final product. You’ll need to wear the sizing ring for at least 24 hours (and ideally through normal daily activities) to check comfort, swelling, finger variation. Bottom line: If you’re buying the Oura Ring 4, get the sizing kit first. It takes away a lot of guesswork and prevents the hassle of ordering a ring that’s too loose or too tight. Measure your finger, test it over a day or two, pick the best fit — then buy the actual ring. This way your investment pays off and you get the full benefit of the ring.

The wife asked for this for Xmas. She wanted it bigger to fit on her thumb. The sizing box was great too she was able to pick the exact size she wanted and then no exchanges and wasting time and effort! She tells me everyday what the ring tells her and it’s starting to gather enough info to help her make corrections or keep doing what she’s doing depending. It’s a little pricey when you see some others at less than $100 but I didn’t dare risk being cheap and than it doesn’t work for her. So, overall she’s happy you get 5 stars!!

Purchased the oura ring after sizing it with this tool. Works perfectly. I am thankful to Amex for their Oura ring promotion, and I am super happy to have invested in the equipment.

後で判明したがアマゾンとその他で1000円近く値段が違う。類似の商品にも出て来なかった。 ２４時間装着とあったので着けて寝たら、かぶれでしまった。本商品とは素材が違うが、高いので怖くて買えない

Great sizing tool. However, Amazon SG doesnt allow the actual Oura Ring to be delivered. The status has been “Ordered Received…”
