Customer Ratings & Reviews

Not much can really be said about a ring sizing kit. The kit contains 12 different sizes, ranging from 4 to 15. I debated, for a while, on getting a size 7 or 8. The instructions say that the ring should fit snug, not loose, that it should be easily removed using soap and water. For me, that indicates that a ring is a bit too snug. For my fingers, having half sizes would have really been helpful. My ring finger on my dominant hand could use a 7.5 and my middle finger on both hands could use an 8.5. I ended up going with a size 7. I can already tell, on occasion, I will need to use soap and water to get the ring off. Currently, our weather/temperature is about 80 degrees. When the temperatures cool down and winter arrives, I'm guessing the size 7 will work just fine. As I mentioned, not much else can be said about this kit. It serves the function it supposed to when looking to buy an Oura ring. Now that I know what size I need, I have this whole kit that I have no use for. Perhaps Oura should have some kind of recycling program for the kit.

I'll start with this: I think it's strange to write a review on a sizing kit independent of the product for which the sizing kit is intended. That said, I do have some thoughts about Oura's sizing kit for their Ring Gen 4. The packaging is light and simple, which I'm growing to really appreciate. Overly obnoxious packaging that is intended to elevate a products quality is…well, obnoxious. I appreciate that Oura is minimizing their footprint for packaging a product that for most people will end up in the garbage. Additionally, I appreciate that while this product has a price tag, if your intention is to purchase the ring, you end up getting the cost of the product credited to your purchase of the ring. I'm not certain that includes sales tax, but you know, Uncle Sam needs his cut, even if it seems "free." As far as a ring sizing kit is concerned, it's fine. I get the necessity behind the thing, especially because Oura rings are a "one size fits one" product. The sizing kit suggests you wear the ring on your preferred finger for at least 24 hours to ensure comfort, but I've heard/read that Oura themselves suggests in the ring's packaging to where the ring on your index finger. If that's true, it's a bit misleading, but I also don't know how much performance of the ring will suffer as a result of NOT wearing it on your index finger. But again, this isn't really supposed to be about the Oura ring, so I'll save my judgements for the full Oura review. Smart Watch companies have been getting around the sizing issue for years with paper-printed templates; this is economical, environmentally friendly (moreso that a shipped package), and simple. I get that rings aren't watch bands, but I'm not entirely convinced shipping hundreds/thousands of packages of plastic rings that will end up in a landfill is the move. I am, of course, assuming these are plastic. Maybe they're some fancy type of biodegradable material that have plant seeds embedded in them, that could be planted in your backyard and actually have a positive environmental impact. Or, maybe they could be made of a dense paper material combined with a pine resin that easily burns, so could be used as a firestarter for your campfire. But, the package doesn't indicate that's the case, so, into the trash with these. I've become used to forced obsolescence with technology, but it's very strange to see it applied to a truly non-tech product that has an intentionally limited use case and lifespan. (I've also heard other people give them to their kids to be colored/drawn on, which is a reasonably good use of the wasted plastic, I guess.) So, I don't know. Do I recommend it? I guess I kind of have to, because it's a necessary cost of admission for the Oura ring. And yes, it doesn't cost me anything, technically. But there is a cost, and I'm not convinced that it's necessary. Hopefully, "three stars" is a good way to covey all of this.

Helped so much I wore it for a week before I bought my Oura ring

helped me understand which size I needed. Bought the oura ring as a gift...giving the sizing kit allowed them to determine which size they really needed before buying. Came with a $10 gift card too which essentially made it free.
