The first thing I noticed is that you can flip it so the gold side faces out, and it just looks like a clean gold band. The LED display faces your palm underneath so you can still check your step count and stats discreetly — best of both worlds aesthetically and functionally.
The vibration feature for text message notifications is genuinely useful — a subtle buzz on your finger so you never miss a message without having to check your phone. It's discreet enough that it doesn't feel intrusive but noticeable enough to actually work.
The gold finish is really polished and premium looking on the hand. It sits flat and comfortable and doesn't look bulky or techy from the outside at all. Tracks all the basics — steps, sleep, heart rate, blood oxygen — without any subscription fees which is a big plus.
If you want health tracking but don't want to broadcast that you're wearing a fitness device, the way this one wears is genuinely clever.

The ring fits well. It’s a bit thicker than a regular ring, so it takes some getting used to. The vibration is gentle and works well for quiet reminders throughout the day. I wouldn’t rely on it to wake me up, but for everyday reminders, it does the job well.

Overall I was impressed with the quality of the ring. It looks good and does what it says. My only negatives are that the vibration alerts are quite weak and hard to notice, and that I wish the 2 day battery life was longer.

I really like this ring for days I don’t want to wear my Apple Watch. Tracks my steps probably even better. It vibrates for calls but doesn’t seem to vibrate for text messages which I really was hoping for

The sleep application is not working. My finger keeps bumping a button and it changes everything.
We're sorry to hear about the sleep tracking and accidental button presses. This isn't the experience we want you to have with your SY1. We've reached out to you directly to better understand what's happening and help resolve both issues. Thank you for bringing this to our attention!

I couldn't be happier with my purchase! The product quality completely exceeded my expectations—it is exceptionally well-made, works flawlessly, and feels premium in every way. But what truly set this experience apart was their post-sales service. I had a quick query after receiving my order, and the support team responded immediately, handling everything with incredible efficiency, kindness, and professionalism. It is rare to find a company that cares this much about their customers after the sale is complete. 10/10, would highly recommend to anyone!

Light weight, robust construction, sizing perfect, great screen, visible in bright light with the option to turn the screen off in the app ,easy to navigate the information on the ring it uses both red and green diodes to measure SP02/hart/steeps sleep etc... reasonable battery life, with the screen active I got around 48 hours and with the screen off I'm getting double that number. Good app integration pairs up and works as intended. Why pay more for a western branded smart ring that basically dose the same, value for money overall.

I like it a lot very useful can wait to see how company grows
