“Works seamlessly, connectivity great. Still testing, but so far good, durable product with excellent battery life. The no subscription model is one of the things that stands out about this ring and CUDIS project.”

“The ring looks very high quality, fits perfectly and is comfortable to wear. The PRIME BLACK color is elegant and matches everything. Delivery was fast and the packaging was nice. I'm very satisfied and definitely recommend it.”

“Great ring! I can measure my heart rate, making steps and get final amount during the day. Sleep score is awesome and also stress level for me very important. Sport activity with how many calories I burned. Very comfortable ring to use and looks very fancy and modern. I love it! App working very fine also!”

“Really impressed with the design and comfort. I love how it combines sporty energy with a premium look — definitely stands out from regular accessories.”

“I'm so happy to get the ring I've been waiting for. I'm working out by wearing it together every day now. It's fun to check your health and raise your gym points.”

“001, 002, sporty ring… best is 002. I like simple design. And very comfortable fit for me. I forgot that I was wearing 002.”

“It's a great product. Nice app. I really appreciate the features. Battery life is crazy good. Issues I had: one connection issue where I needed to reset the app. Also, it would be nice if there was a tactile bump on both sides of the ring to help identify where the sensors are. Overall, very happy with the purchase.”

“Everything was SMOOTH. Since I started wearing the CUDIS ring, I've become more aware of my lifestyle. Not only have I been seizing small moments throughout the day to stay active, but I've also started paying closer attention to my sleep schedule and quality.”

“I went up a size from my previous ring to wear it on my middle finger, and it fits perfectly. I chose this color because I love blue, and I really like it. Two replacement ones are also included so even if one gets dirty, it can still be kept in like-new condition.”

“I've been using it for about a week now, and the device feels great. Comfortable to wear — the ring is a bit thick, but that's unavoidable for its functionality. It would be nice if it were thinner. Overall, the connection is good.”

“I think it's even more stylish. It's nice to have a dedicated charger and a spare rubber ring. I'd love to try all the colors. Great ring!”

“I'm quite pleased. The response is fast and the design is pretty. It's also good as a fashion ring.”

“Thank you for the prompt delivery. Really like the ring, now I can track my vitals. Also I like the material it is made of. Thank you to the team, I wish development.”

“Great fit and is very satisfying to use the UI for it. Not a paid reviewer lol, but genuinely enjoy the process of this. Great product, would recommend!”

“Very good however I would like more insight into the raw health data.”

“Very good all around. The only thing for improvement is the connection. The connection goes away sometimes.”

“The ring is great, however it runs larger than the first CUDIS ring so it doesn't fit properly. Had I known this prior I would have purchased one size smaller.”

“I'm generally satisfied with it. I felt it would be better if the ring's thickness were a little thinner, and it tends to get caught on edges. I really like the wide variety of colors and the design! I look forward to its future improvements!”
