Title: great to find your oura size but waste of packaging
Review: it obviously did what it was supposed to do which was help me find my size oura ring before purchasing but the back of the box clearly states to return the sizing kit to amazon. when i attempted to initiate a return, amazon customer service says they didnt need it back and now i feel bad tossing the entire kit that was barely used. i liked the idea of recycling the kit for another customer but i guess ill just toss it instead. just a heads up that you will get the $10 credit as it mentions towards your real ring purchase but then youre stuck with this box full of plastic rings and its like cool. landfill it is.

Review: Hey bought this ring sizer kits I’ve been on the search for some type of sleep tracker heart monitor blood pressure monitor for a while and all of the reviews that I’ve seen thus far I wore the size that fit me on my finger for quite a while there was no issues with the little nubs on the inside They did not bother me whatsoever They I suffer from old host of autoimmune illnesses and neurological issues so sometimes jewelry and certain things can trigger a bad response on my nerves the nerve endings and within my body and cause extreme debilitating pain That was not the case I have not ordered the ring itself and not as only because I am one of those moms that never spends money on myself and it is an extremely expensive item I had purchase another item to help with hot flashes several years back and my husband actually purchased it for me and I was heartbroken at how ineffective that device was however with all of the affordable options out there I still have not purchased one I am still doing as much research as possible to ensure that I choose the best tracker possible for what I am needing it for and I do not need all of the extra things that come in a smartwatch which is what drew me to the ring in the first place however I am also not wanting to be locked into or have to depend on a monthly subscription and order for my device to work so I am just weighing all my options but this is a solid 5 out of 5 I have no issues with this product whatsoever and I will keep everyone posted if or when I order the actual product itself!

Title: A Necessary Must for OURA RINGS
Review: It seemed silly to get this to use one time – but you have to have the right size of ring to use the OURA System! I was also afraid the sizes may not equate to a jewelers sizes – so I bit the bullet and bought this! You get the money back when you order the ring too!I love my OURA RING – but it is taking a lot of time to figure out exactly how to use the monitoring to improve my health.

Title: Somehow required to figure out what Oura ring size you need… but…
Review: Well, I think it’s slightly smaller than actual Oura ring v3 real sizes are (at least for size 12)Be aware that the actual ring feels a bit “bulkier” than the sizing ring.I would recommend the wear the sizing ring for at least 1 week if not 2 weeks, in cold weather and hot weather. Fingers swollen a lot when it’s hot, and shrink when cold.It will give you the range of size you need.Keep in mind that the Oura ring needs to be quite tight or the measures won’t be good.So the compromise is not easy to do as there are no 1/2 size.And it’s stop at 14! I needed a 15 for my index, 14 is too tight. I can’t wear it on the major due to an injury and 14 is too big the the annular finger. So I had not other choice than going for 12 on the annular.But it’s not the best.

Title: If you’re on the fence about an Oura Ring, get this!
Review: I bought this sizing kit in anticipation of buying an Oura ring during Prime Day, or any other sale. I tried it on several fingers. On both hands. I found the size I needed, but I also discovered that I HATED HAVING THIS THING ON MY FINGER. This little kit saved me hundreds of dollars. Best $10 I’ve ever spent.

Title: Deceptive marketing.
Review: WARNING: This Kit CANNOT be returned if you don’t plan on buying the Oura ring!The rings in these sizing kits come with 3 very uncomfortable bumps which I assume are places for the sensors in the Oura ring. These annoying bumps are the reason why I don’t plan on buying the Oura ring. The only option when trying to return this kit is “Troubleshooting” and that’s it. You will not get a refund for these if you don’t plan on buying the Oura ring.This is malicious by design. Oura will not be having my business.

Review: Sizing is not the same as it is for jewelry rings! Fingers swell and unswell during the day due to preasure, heat, liquid retention, etc. So itâs important to see how it fits throughout a whole 24-hour period. I started thinking I was size 7 and ended up trying -and ordering- a size 8. Great idea ordering the sizing kit before ordering my ring, plus you get $10 credit toward your ring purchase.
