ULTRAHUMAN Ring AIR (Certified Renewed) – Smart Ring Health Tracker, Sleep Tracker, Smart Ring for Men/Women, Fitness Tracker (Sizing Kit, Sizing Kit)

The fit and quality is top notch. Very lightweight. Running it in varying modes gives you a vast array of details. Sleep tracking and stress levels show great detail and improvement techniques. Running it in turbo mode with the most feedback points, the battery life is exceptional. Packaged beautifully and better functionality than all of its predecessors. Fast delivery and easy to set up. Great value for money. All in all, cannot fault the UltraHuman experience.

Overall I love this ring, however has things to be worked on. Sleep tracking is great, but not exercise... Heath improvement tips are really good, but HR sometimes jumps to weird values over night without reason. Battery life id OK, I can live with it! Still giving it 5*, especially with no subscription!

It has given me access to very important information about my health.

I regret buying the Ultrahuman Ring. I really wanted to like it, but my experience has been nothing short of frustrating. The first ring I received didn’t work properly, so I requested a replacement. The second one arrived, and it had the exact same issue. Customer support sent me yet another replacement, and unbelievably, the problem still persists.After going through three devices, I’ve lost all confidence in this product. For something that’s marketed as premium, it’s completely unreliable. Instead of providing useful insights, it has been nothing but a hassle and a waste of money. I would not recommend this product to anyone.
