ULTRAHUMAN Ring AIR - Matte Black- Size 16 - Smart Ring | No Monthly Subscription | Size First with Sizing Kit | Sleep Tracking Wearable - Heart Rate - Fitness Tracker

Very useful sizing kit. It helped me confidently choose the correct ring size before ordering the actual smart ring. Simple to use, clearly marked, and saves the hassle of exchanging the ring later.Can use it later for family and friends to get their ring size.. very handy tool

I have been using the FITTR HART Ring for some time now and have had a very positive experience. The ring is lightweight, comfortable to wear throughout the day, and provides useful insights into key health metrics such as sleep, activity, recovery, heart rate, and overall wellness.What I particularly like is the detailed sleep analysis and readiness score, which help me better understand my daily fitness and recovery levels. The battery life is good, and the companion app is easy to use and presents the data in a simple and meaningful way.The ring has helped me become more aware of my lifestyle habits and make better decisions regarding exercise, sleep, and recovery. Overall, I find the HART Ring to be a valuable health and fitness companion and would recommend it to anyone looking for a convenient wearable for wellness tracking.Highly recommended!

Worst product , needs charging frequently gets disconnected to the paired device and thus data is lost the app is changed and seems built on ai which make it look more fakeDon’t buy it for the price it comes for and now support even … better products available… not happy at all with such expensive ring … feels cheated

The ULTRAHUMAN, sizing kit is very useful and generally worth it if you want your smart wearable to fit well — especially for a device you’ll wear all day and night. It helps avoid guesswork and reduces the chance of ordering the wrong size.The sizing rings gives an opportunity to choose from a variety of colours & also a good test over a couple of days and hands/fingers before finalizing one's choice, especially during the seasonal changes like during heat or cold weather.

Good

Más fácil para poder saber tu talla para el ultrahuman ring

Buen producto, pero al final me decidí por otro

Perfect price to be able to buy before hand before ordering the ring itself. They fit exactly like the actual ring and I’m very pleased with my sizing results.

Can’t really complain. It is what I said it is. I went with a different smart ring because I was in between sizes but it was a good product overall

These are great for getting a ring size (if full size) so you are not wasting time ordering and not fitting and they are free
