light
measures everything a regular smartwatch measures and is comfortable while sleeping
entertained me, after waking up he reported that I hadn't slept because she was, for example. hot bedroom: -D
shows a map, too, during the training session where I skated
offered various advice on how to sleep better
motivated to exercise
failure rate is high, I have the 5th piece, always the indies from support helped immediately and finally sent a new one, they didn't want to send me another piece and refunded me the whole amount.
the battery doesn't last long. at the beginning it's good for 3 days, but it quickly deteriorates to 1 day.
frequent problems with pairing, needing to restart, needing a complete reset.
I won't buy another one, I don't have time to go through the trouble of it not working.
price crazy

elegant design and small size and weight
relatively durable
battery life about 6 days
no subscription fee (unlike Oura)
no extra charge for different colours (unlike Oura)
accurate measurement of lots of data
further updates and continuous improvement of functions and data processing and measurement almost every week
from summer 2025 the problem with PCB boards and battery failures should be solved - time will tell, so far everything is without problem
technical support response and customer care UH
the app in English is sometimes translated strangely and often does not use diacritics

works great
The ULTRAHUMAN support directly in the app is perfect - they have sent me a new ring (3 times already) when failures due to long use, they also sent me a charger when they released a new one
alza does not give free sizing kit.

I've had the breast for about half a year and then I left it on the charger for 24 hours and it stopped responding to the phone app, I just wait until it gets wet and buy it again
Super light
It doesn't feel at all on the hand
Take 4-6 days for the chill mode and 2-3 days for the turbo mode
Recommendations for sleep measurement definitely
Chill mode 4-6 days turbo mode 2-3

I've had it for a few days and so far so good, but judging by the reviews I'm afraid of an early complaint, I'll update if I do 😀
The size is fine, it fits with the sizing kit, it's just a bit bigger, but it's nothing noticeable
The size and the ring itself is fine, I have small skinny fingers, so I was worried that it would look chunky, but compared to the Oura ring it looks just fine

otherwise I recommend it and I'm glad I could at least try it. Jindřich Navrátil
Relatively reliable measurement
charging speed
device endurance
the ring is visually beautiful
AFTER A FEW MONTHS I HAD TO RETURN BECAUSE IT COMPLETELY STOPPED REACTING (I did everything according to the instructions and the ring broke on its own) -I don't know if I will buy it again !

After a year I got to the review. So take it for what it is.

Batteries. They don't last in the long run. I've already settled my second claim, where the ring just died. Alza is excellent at this.
Surface treatment. Tungsten carbide as hard as diamond? Forget it, it gets scratched and the paint slowly comes off.
Frequent charging, but this can be solved by update and sleep mode.

Total waste, they changed my ring 5 times because of a faulty battery in one year. I've given up, I'm tired of constantly having to deal with mailings for another junk ring. They tried to shut me up with some bullshit series. Support isn't even responding anymore.
