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 !

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.

High failure rate of the ring
Alza gives new pieces, thus the new warranty does not run
