Review: best smart ring on the market! - best investment of 2025! looks and feels amazing on, very functional - you can track so much on it in real time. especially good if you struggle with sleep as it gives you detailed insights. i managed to get it on a black friday deal (£232) so the value for money was amazing! only con of this ring is that it does scratch easily but this can be mitigated by getting a cover for it.

### ⭐⭐⭐⭐ So far so good....
*by G***. on 26 December 2025*

So far so good. Ring functions well with a few caveats. The times showing wake up etc are generally inaccurate. For example today I was up at 0458 and the ring indicated 0809. This then throws off some of the other stats. Additionally, I would like some more explanation or simplification of the stats and figures in the app as I am quite new at this. The ring looks good but come off periodically while I am doing things around the house. Perhaps I should have sized differently but wear it on my index finger by choice. May have to replace it for different size. Generally I am satisfied but would really like a less complex app UI for us newbies. Will update after further usage.
