Review: Great Product - Great Product does the job on tracking sleep, heart rate, movement etc. Very easy to set up and get going. Would recommend for those that do not want to wear a smart watch.
Review: So So Happy! - I hesitated for a while before investing in this gadget. And I love my Gadgets! but after doing some homework on the competition, I decided to jump for it. First, the fit and metal colour are great, I couldn't be happier, the quality and durability is insane, i do everything with it, I rarely take it off. The connectivity to my Samsung Z Fold6 was flawless, no hiccups, plus, everything you open the app, it updates in no time. so great compatibility. Now, you need to give it time to gather data about you, of course... it will not happen overnight which is quite right, but the intel you get afterwards is great. Your body age, sleep quality, energy available, your stress, it is such a great little ring. it is a lot of money for such a small device but the value for money is worth it. I highly recommend it if you are curious and want to be nudge in the right direction for better health.

### ⭐⭐⭐⭐⭐ A great tool which does exactly what it says.
*by T***P on 12 December 2025*

The app is brilliant. It takes a while to get to know you, so don't expect instant insights, but as it builds a picture it is really good at telling you what's going on. I am using it to track my food etc as well, so not exclusively related to what's happening on the ring. On the ring specifically? Well, it is chunkier than a ring you'd buy as jewellery. That's ok and it's not ridiculous, but you have to get used to it. I do find I take it off and put it on more, or change fingers, as my hand needs a rest. The colour... Despite the name stealth, does stand out. If you want something more subtle then brushed or silver is probably better, as it's more like typical jewellery. That being said, I've gotten used to it. Sizing - definitely get the sizing kit and wear not for a few mins but for a day or two to understand how your fingers change size. Battery life is good. I reckon 8 charge it once every 4 otlr 5 days so far. I understand turning off blood oxygen measuring is the way to really eek out more battery life. You can also use airplane mode to reduce how often it speaks to your phone. But yeah, no regrets, it's a great tool and honestly, easier to live with than a smart watch.
