YWXTW Invisible Grips for Oura Ring Size Adjuster Waterproof Adhesive Guard Compatible with Samsung Ultrahuman Ring Thinner Sizers

Update! Company sent immediate Replacements that work very well. They were urgently communicating with me to make this right! Well done. Not sure how to give zero stars. The adhesive does not work and the sizer slips out. I tried 2 of them and the same thing occurred with both sizers. Once even popped off the ring while k. My finger into the cheesecake I was making. They fit snug on the ring but do NOT stick and slide around. Very disappointed. Read more

They are not in invisible as stated. The adhesive does not keep it in place so it does have a tendency to slide down to where the sensors are located. Does solve the half sizing problem with the Oura rings if you don’t mind adjusting many times during the day, especially after washing your hands. You do have to remove it to charge the ring.

These are BAD. They do NOT stay on. The first 2 sizes were instantly ruined because the adhesive peeled off of both of them. The rest don't fit. Wasted money. Read more

Been losing weight and needed something to help keep my Oura on my finger. Tried these, and at first I didn’t “get it” on how to use them. I expected some sort of stickiness to hold the sizer to the Oura. But this is much simpler than that. For my ring, I put the sizer in the right spot (where there are no sensors) inside the ring and slid the ring and sizer onto my finger. Sounds like it wouldn’t work, but it really does. My Oura no longer falls off my fingers! Yay! I’ve had the same sizer on for about 2 weeks now. I imagine when i lose more weight, I’ll add 2 sizers instead of one. They seem to stack so hopefully so. Overall, easy to use, good price point, good quantity included in the pack, good instructions and these don’t foul up your ring permanently either. Very good product. Read more

The product works well enough. However, you must remove the spacer to charge the ring. Read more

I don’t even notice I’m wearing the sizer. I lost enough weight recently that my ring was too loose. I just slip this on the inside and it’s secure without any type of adhesive or anything. I also have enough room now that I can sorta roll it out from under the ring while it’s on my finger so it slides over my knuckle easier (still secure enough, though, that it’s not going to do it on its own). All in all, I’m very pleased with this and it has saved me from having to buy another Oura ring. Read more

I have the Oura Ring 4 and this product works exactly as intended. I had lost a little weight from reducing carbs and always pairing them with a protein, but apparently my pointer finger slimmed down as well to the point where I was concerned that my Oura ring might slip off when I'm out and about and not paying attention. In other words, the ring still fit me, but if my finger happened to be facing downwards and I moved it around it a certain way 'could' just slip off from time to time. I used one of these and the fit was perfect...not too tight...the ring fit great. The adjuster piece feels like a stiff silicone (that is still flexible), and has a sticky adhesive kind of like glue dots so you can take the adjuster on and off as needed (until it loses its stickiness eventually). I can appreciate it comes in a pack of 8. My only concern is that there is no way to wear the adjuster without covering up at least one sensor on the Oura Ring 4. The ring has one main sensor, and 3 more smaller ones spread on other insides of the ring. I avoided the main sensor, but the adjuster still covers at least one of the smaller sensors. When looking at my stats later on, I don't 'think' it affected the data, but I can't be sure. Overall, this adjuster is great and works as intended. It's comfortable and I'm confident that the ring won't fall off without me knowing. Read more

Definitely makes your ring a size smaller. And like that i can take on/off easy! Read more
