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 alternative to a smart-watch
*by S***Y on 16 June 2025*

I was keen to utilise technology to help with my fitness, but love mechanical watches so a smart-watch wasn't an option. Came across this and after some research I gave it a punt. Very happy customer, the ring is a doddle to set up and works a treat. Battery life is a snadge less than advertised but not enough to make me dock points. It's a shame about the subscription, as I think the ring is costly enough that it's something of a liberty to charge for ongoing use, they could lose things like the guided meditation etc and give a free option, or bake in more value-add to the app. Enough moaning though, what it does it does really well, giving me insights into my sleep patterns and broader health. I am happy I bought it and check the app at least daily months after buying.
