small rings/ inaccurate
Dagins—November 28, 2025
update: I can say with absolute certainty that my ring doesn't work. I got it mostly to track my sleep and blood pressure and it doesn't register when I wake up at all and gives me way more steps than possible. I will be returning... I just got my TIAZUUX ring. The size doesn't match the sampler which is the whole purpose of buying this. the real ring is a smidge bigger. (sizing kit) I've never been a ring guy so it's hard to really judge. I know compared to some I may have big hands, but I've known others that were larger, at an old job my hands were sized as 11.5 and had to wear size 12 gloves, some of the other guys actually were size 12+ so I don't think my hands are abnormally large. All that said i can only fit the size 13 on my nondominant ring finger, which is definingly snug. I can put it on and pull it off ok but if I leave it on, i have to twist it to remove...(can fit size 12 on my pinky but am under the impression smart rings should be on one of the 3 center fingers for most accurate results) So heads up to anyone with large hands that this might not be the brand for you...

Now I know the right size

They take the guess work out of finding the correct size. You can wear it for a day or more to be sure its the right fit. They are made of a high quality plastic that's light and comfortable Read more

Sizing kit
J. Rosenberg—April 18, 2025
I ordered the sizing kit, and it is close to what I'd expect for ring sizing, but not exactly. It's too bad they don't have half sizes available. Read more
