Review: A Game-Changer for Health and Performance: The Ultrahuman Ring AIR - I've been using the Ultrahuman Ring AIR for a few weeks now, and I can confidently say it’s one of the most impressive fitness trackers I’ve ever used. As someone who’s deeply invested in both physical performance and overall well-being, this device checks all the right boxes. Design and Comfort: First off, the design is sleek and minimalistic, which is exactly what I was looking for. The ring is lightweight and incredibly comfortable to wear—almost forgettable during the day. It's made with high-quality materials that feel premium, and the matte finish gives it a sophisticated look. Whether I’m working out or just going about my daily activities, it blends seamlessly into my routine. Health Insights: The Ultrahuman Ring AIR is packed with sensors that provide in-depth insights into your body’s performance and recovery. The most standout feature for me has been its ability to track heart rate variability (HRV) and sleep quality—two metrics I rely heavily on to optimize my workouts and recovery. It also measures things like respiratory rate, body temperature trends, and activity levels throughout the day, making it easy to stay on top of my health. Battery Life: Another impressive feature is its battery life. With regular use, I’m getting around 4-5 days on a single charge. It charges quickly too, so I never have to be without it for long. Ultrahuman App: The Ultrahuman app is another highlight. It’s super intuitive and provides a clear, easy-to-understand breakdown of all the data.

### ⭐ Subhuman.. hazardous and traumatic ! Pls read before buying
*by D***J on 20 December 2025*

This review is not a reflection on the features of the ring which I am sure are good , but a fatal flaw in design from which I greatly suffered. Please read the experience below and know very well that there is a small chance this could be you …and think whether is a worth buying such a device I was using the ring for a few days when it got stuck at the bottom of my middle fingers and started to cause discomfort and swelling. As in the case of any normal ring , after failing to pull it off I went to a jeweller shop where they tried a variety of devices which simply could not cut through the strong material. Finally they took out a mini electric saw cutter which also failed to open a ring. The jeweller said that his devices were made for soft metals like gold , and that o would have to find a specialised machine to cut through titanium. It’s now 12:30 am , my swelling is out of control, what am I supposed to do ?? Now frantic with increased discomfort, I messaged customer support on the app ( they don’t have a number) who asked me to proceed to the Emergency Room. However , The doctors in the ER were equally perplexed about how to cut through this material , I frantically asked the support about which tool / power instrument could be used , they had absolutely no answer! There was also the added problem of a battery in the ring , and how to cut through that and with which instrument. Imagine an electrical cutter going through an inflammable battery. My finger by this time had swelled into a baloon, and I had no idea what to do next. We were frantically calling Emergency Rooms at 1 am in the morning , asking them if they had the required tools to break open the titanium band, two of the most premier hospitals in Delhi said that they did not, and only AIIMS had a bone saw cutter that could do the job. We were told that it is a trauma filled experience at AIIMS and decided to try apollo first. Imagine a ring that is Suppose to be a boon to your health becomes a Heath hazard , that simply cannot be taken off. To cut the story short, after multiple tries the ring finally came off at 2:30 am in the morning when a team of skilled plastic surgeons and doctors at apollo hospital finally got the off with the greatest difficultly. Literally 5 full size men had to exert all their cumulative muscle to slowly and painfully cut through the metal using a specialised device. Not only does the ring have absolutely no safety protocol , but there is zero information of how and where it can be cut off during a dire emergency like this. The worst part is the company simply doesn’t care about this hazardous malfunction in the product , after trying to get repeated information from them about the lack of support , guidelines , emergency protocol and statutory safety compliance , they did not even bother call and check on me , and simply offered to replace or refund the ring ( like I would ever wear their ring again). I don’t want anyone to go through , what proved to be one of the worst nights of my entire life, with my whole family sitting outside a ER and the doctor at one point of time bringing out an amputation to try different tools from it. The likelihood is that a situation like this would probably not reoccur with you , but I think you should be well aware of the possible consequences ( however remote ) of using this device. Especially when a company shows blatant disregard to such concerns.
