## Description

ULTRAHUMAN Ring AIR - Matte Grey - Size 11 - Smart Ring | No Monthly Subscription | Size First with Sizing Kit | Sleep Tracking Wearable - Heart Rate - Fitness Tracker : desertcart.co.uk: Sports & Outdoors

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.
Review: Great product. - I am happy with the functionality of this ring. The stats mirror fairly closely to my Apple Watch in terms of sleep. Steps are not at all accurate though. The app provides lots of information, which I love, although it could be overwhelming for some. That said, it breaks it down well and gives some well presented information The ring is well made and solid, and looks good. So far I am very happy with the product.
