Purchase sizing kit first to get the perfect ring AIR size. Ring AIR is available in 10 sizes from 5-14. - TRYING THE SIZING RING - It is important to first use the sizing kit to determine the ring AIR size. Wear your ring sizer for at least 24 hours to know your fit. Wear the ring such that the engraved size number is toward the palm of your hand. - FINDING THE CORRECT FINGER - For optimal comfort and advanced sleep tracking, we recommend you wear the Ultrahuman Ring AIR on your index, middle, or ring finger. - FIT CHECK: You will get highest data accuracy and optimal comfort with a properly fitting Ultrahuman Ring. Here are a few simple ways to assess this — If you rotate the ring on your finger, it should not rotate freely. - CHOOSE YOUR RING: After you've precisely determined your size using our sizing kit, head over to desertcart to order your Ultrahuman Smart Ring. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D8HYRS46 | | Are Batteries Included | No | | Average Battery Life (in hours) | 6 Days | | Batteries | 1 Lithium Polymer batteries required. | | Brand | ULTRAHUMAN | | Colour | Swatch Sizing Kit | | Customer Reviews | 4.5 4.5 out of 5 stars (1,489) | | Date First Available | 7 July 2024 | | Generic Name | Ultrahuman Ring AIR Sizing Kit | | Included Components | Sizing Kit Guide | | Item Dimensions LxWxH | 20 x 8 x 20 Millimeters | | Item Height | 20 Millimeters | | Item Weight | 3.7 g | | Item Width | 8 Millimeters | | Item model number | UHRA-SSK-US | | Lithium Battery Energy Content | 0.09 Watt Hours | | Lithium Battery Weight | 0.7 Grams | | Manufacturer | Ultrahuman Healthcare Pvt Ltd | | Net Quantity | 1 Count | | Operating System | android | | Packer | Ultrahuman Healthcare PVT LTD, No. 4088/799, Third Floor, V K Paradise Sector-2HSR Layout, Bangalore Karnataka 560102 India, Contact - 18001028693, cyborg@ultrahuman.com | | Product Dimensions | 2 x 0.8 x 2 cm; 3.7 g | | Series | Ultrahuman Ring AIR Sizing Kit | | Wireless Type | Bluetooth | ## Product Details - **Connectivity Technology:** Not Required - **Memory Storage Capacity:** 0.5 MB - **Operating System:** android - **Special Feature:** anti-scratches - **Wireless Communication Standard:** Bluetooth ## Images ![ULTRAHUMAN Ring AIR Sizing Kit with Colours - Size First Before You Buy - Choose from 10 Sizes - Sizes 5 to 14 from 5 Colour Options- Find The Perfect Ring Size - Smart Ring Sizer - Image 1](https://m.media-amazon.com/images/I/413wLCkhA6L.jpg) ![ULTRAHUMAN Ring AIR Sizing Kit with Colours - Size First Before You Buy - Choose from 10 Sizes - Sizes 5 to 14 from 5 Colour Options- Find The Perfect Ring Size - Smart Ring Sizer - Image 2](https://m.media-amazon.com/images/I/41EL2PAv7yL.jpg) ![ULTRAHUMAN Ring AIR Sizing Kit with Colours - Size First Before You Buy - Choose from 10 Sizes - Sizes 5 to 14 from 5 Colour Options- Find The Perfect Ring Size - Smart Ring Sizer - Image 3](https://m.media-amazon.com/images/I/41YGRVs00hL.jpg) ![ULTRAHUMAN Ring AIR Sizing Kit with Colours - Size First Before You Buy - Choose from 10 Sizes - Sizes 5 to 14 from 5 Colour Options- Find The Perfect Ring Size - Smart Ring Sizer - Image 4](https://m.media-amazon.com/images/I/41YOjAyz6cL.jpg) ![ULTRAHUMAN Ring AIR Sizing Kit with Colours - Size First Before You Buy - Choose from 10 Sizes - Sizes 5 to 14 from 5 Colour Options- Find The Perfect Ring Size - Smart Ring Sizer - Image 5](https://m.media-amazon.com/images/I/41dLbjuMbuL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***S on 6 November 2025* Excelente Producto ### ⭐⭐⭐⭐⭐ Review *by C***K on 21 December 2025* This was so useful to find out my right ring size.
