Daher habe ein Auge auf den Ultrahuman Ring Air geworfen. Allerdings wollte ich den Ring auf deren Homepage nicht zuerst bestellen und dann erst das Sizing Kit bekommen. Daher habe ich es hier günstig bestellt und bekam es innerhalb weniger Tage zugeschickt. Das Sizing Kit ist super gut verpackt. Es liegen Probierringe in allen angebotenen Größen bei. Die Ringe sind gut gemacht und exakt die gleiche Größe wie die echten Ringe. Ich konnte für mich mit diesem Kit die perfekte Ringgröße bestimmen. Als Tipp: Tragt den Ringe mehrere Tage und auch beim Duschen und beim Schlafen. Dann wisst ihr genau, ob er passt. ## Frequently Bought Together - Ultrahuman Ring AIR - Advanced sleep-tracking wearable, HRV, Heart rate & temperature monitoring, Track workout, movement & recovery, Water resistant up to 100 m, 6 days battery life - Oura Ring 4 Sizing Kit - Size Before You Buy - Unique Sizing Classification for Smart Rings - Receive Credit for Purchase --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/550402486-ultrahuman-ring-air-advanced-sleep-tracking-wearable-hrv-heart-rate](https://www.desertcart.us/products/550402486-ultrahuman-ring-air-advanced-sleep-tracking-wearable-hrv-heart-rate) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-06-24*
