## Description

Product Description ultrahuman ring AIR

Review: Frustrating Experience with Ultrahuman Ring Air - I have been using the Ultrahuman Ring Air for a few months. The ring design, comfort, and tracking experience were good initially, but recently the device completely stopped connecting and syncing with the app. I followed all troubleshooting steps suggested by the app and support team, including reset procedures, but the issue still remains unresolved. What is more disappointing is that even after raising a warranty support request and sharing the invoice and device details, I still have not received a proper response or resolution from customer care. For a premium-priced smart wearable, both device reliability and after-sales support should be much better. Currently disappointed with: - Connectivity reliability - Delay in customer support response - Lack of timely resolution I hope the team responds soon and improves the overall customer support experience.
Review: Excellent health insights, comfortable to wear and great battery life - I recently started using the Ultrahuman Ring and my experience so far has been very positive. Quick Highlights: Very lightweight and comfortable to wear, especially during sleep. Excellent analytics and health insights in the Ultrahuman app. Automatic nap detection works very well. Battery lasts around 4 days on a full charge. One of the biggest advantages for me is that I no longer need to wear a smartwatch during sleep. The ring is lightweight, comfortable, and hardly noticeable while sleeping. The analytics and insights provided in the Ultrahuman app are top class. The level of detail around sleep quality, recovery, HRV, movement, and overall health metrics is very impressive. It actually takes some time to fully understand all the insights and how to use them to improve different health parameters, and I feel it will take me a couple of weeks to explore everything properly. Another feature I really liked is the automatic nap detection. Even if I sleep for a short time during the day, the ring detects the nap automatically and records it in the app, which contributes to the overall sleep analysis and sleep score. The battery life is also very good. Once fully charged, I do not need to worry about charging it for around four days, which makes it very convenient for daily use. Overall, it is a great product and a very useful addition for anyone who wants to improve their health routine and understand their body better.

### ⭐ Missed greatness - a beta product which should be stopped immediately !
*by R***S on 11 August 2024*

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 Amazon - 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.
