Review: Missed greatness - a beta product which should be stopped immediately ! - I took great pride in skipping the Oura ring and the Whoop strap for something INDIAN ! Only to be disappointed - great potential but poorly implemented. Pros - 1. Great details and analysis as a potential (not delivered) 2. Easy to wear 3. Indian tech without any subscription fee except for some advanced features 4. Excellent customer care - replacement happened in three days of the complaint Cons - 1. Poor quality - the Bluetooth modules keep failing - happened on two of my rings 2. Spotty and occasional connection to the app / phone 3. Gets too hot when charging even with a low wattage charger 4. Misses some or even major part of the sleep - happened on two of my devices. Sadly the replacement came through customer care and not through desertcart - where a new replacement or return window would have been open. Now I am stuck with two redundant pieces of tech ! On a positive note - I am proud that an Indian company has done this complicated device. But I am disappointed that they did not spend much on quality control ! Unnecessary spending - maybe Oura or even the cheap Gabit may be better. Hope Ultrahuman recalls the devices and refunds the money. Seems highly unlikely - though they appear passionate about the product it is still a business after all ! Till they rectify folks - let us explore Garmin Venu 3 (working well so far) ; Apple Watch or wait for TCO of Oura to fall.
Review: The Most Seamless Way to Track Sleep and Recovery - After using couple of trackers (Amazfit, AppleWatch, PixelWatch), I thought to switch to a device that I can wear easily while sleeping. I found Ultrahuman ring air as an option to try, with its minimalist profile and titanium construction, it felt like the right move for 24/7 tracking without the bulk of a traditional smartwatch. After wearing it for a few weeks, I can say it has exceeded my expectations in several key areas. Battery and Build The battery life is good (not super good when you are on turbo mode), easily lasting 4 days on a single charge, which is a massive relief compared to the daily charging routine of most smartwatches. Despite its lightweight feel, the build quality is incredibly robust. It handles daily wear and tear effortlessly, and I never worry about scuffing it during my day-to-day activities. Seamless Tracking What really stands out is how the ring stays out of the way until you need the data. It automatically detects my workouts with surprising accuracy, so I don't have to manually start a session every time I hit the gym or go for a walk. Intuitive Experience The companion app is a highlight as well. It’s very intuitive, presenting complex health metrics like sleep stages and recovery scores in a way that’s easy to understand and act upon. It provides a holistic view of my health without feeling overwhelming. Final Verdict If you are looking for a screen-free way to monitor your health that is comfortable enough to wear overnight and tough enough for any workout, the Ultrahuman Ring Air is a fantastic choice. It has successfully replaced my bulky watches for sleep and recovery tracking.

### ⭐ Terrible Terrible support run by a useless AI agent to service an unstable 20K device
*by N***S on 14 June 2026*

For all its features would give it a negative star for product stability and a minus 5 star for terrible customer service. The AI agent tries various tests and keeps repeating them as it cannot register results. Since the ring is not connecting to app its not surprising that it cannot register. As a customer who bought both the ring and home product the quality of customer service and product is sad. This is a 2nd replacement I am asking for within 6 months and this one from last 3 months. For 20K plus device its a sheer waste of money. Am highly disappointed with their customer support.
