Battery life pathetic

Battery life pathetic
The battery holds barely enough charge to get through 12 hours continuously monitoring. Also I have had the ring less than a month and already the side piece is broken making it no longer a option to wear on a middle finger or risk getting cut. Sad showing.

I'm a figure skater and sometimes while doing our program HR is not picked up. Battery life could be longer. And sometimes have to tell it to record sleep patterns when I thought it did it automatically. Other then that love the compact size.

1.0 out of 5 stars Medical doctor review. Not returnable. Doesn't work as advertised.
Reviewed in the United States on July 17, 2021

I am a medical doctor. I was intrigued by the apparent simplicity and unobtrusivness of this product for both personal use and possibly for my patients.

Despite the reviews, I gave it a shot.

Without getting into too much technical detail, I will just say that I was surprised by both day and overnight values and patterns.
They simply didn't add up medically.

I have 2 other devices (one consumer grade and 1 medical grade) and brought another one home from work. I compared the 4 devices against each other across various times and over a 2 week period.

All mfg instructions were carefully followed and for the ring, multiple fingers were used.

Bottom line: the 3 other devices show a high degree of internal consistency and the patterns of variability matched other physiologic parameters appropriately.

This device showed striking inaccuracies more than 40% of the time. These types of inaccuracies and their degree could EASILY lead a personal physician to be alarmed and to order unnecessary testing and consultation. Pulmonary function testing, sleep studies, echocardiograms and the like are expensive. With all testing comes the risk of false positive results leading to further testing. Testing in these situations is not free of risk of harm.

After a general 'customer with an issue' email, in subsequent mails (2) I expressed my concerns and offered my assistance and data to the company (for free). After an initial reply to my first general email, requesting my contact information (in retrospect probably automated), my communications were ignored.

Again, this device is NOT RETURNABLE and is so willfully inaccurate that we are looking into which agency and process to use to report it.

The company does not respond.

4.0 out of 5 stars Good but needs improvements
Reviewed in the United States on April 3, 2021

Love the product idea.
This did much more than measure heart rate and sleep quality for me. I ve used it to manage my temper & emotions.

Controling your heart rate and keeping it below a certain level guarantees you never get mad essentially and forces you to pace yourself when discussing with other people.

WHY 4 STARS AND NOT 5?
Accuracy appears to be somewhat poor. Possibly because I picked the large ring which is rather big, but the small one would be too small for me and cut blood circulation.

In particular this is not very good at tracking fast heart rate (above 100-120) which occurs frequently during a workout and is important to track (eg i need to know if im at 120 or 160... but it seems it stays stuck in the low 100’s)

The charger for the unit broke in about 90 days. There is no way to request a replacement charger or request a service repair. The manufacturers website is very basic with little ability to access product support. 90 days later, and with no ability to access support, the unit is effectively useless. Disappointing!

My first ring would only work for about 6 hours. Emailed customer service and received a personal phone call from Neil who shipped a replacement quickly. No problems with the replacement and will definitely recommend this product to anyone looking for a fitness ring. The app can use some more work but customer service is more than 5 stars.

3.0 out of 5 stars Bulky and cumbersome.
Reviewed in the United States on March 2, 2024
Verified Purchase
It's a lot more intrusive than it appears in the pictures. I felt like it was getting in the way of using my hand; the pad especially dug into the inside of my finger when I lifted heavy things.
The app is clunky and not very user friendly. You have to tell it you're going to sleep, or it won't monitor and analyze your sleep. In fact you have to tell it you're starting an activity or it won't analyze anything at all.

I sent it back. I wanted something to track my life, not something to control my life
