Customer Reviews

Sleep apnea test -
After wearing it for three nights, Belun® sent me a detailed sleep apnea report with charts and detection. The report confirmed that I did not have sleep apnea. I highly recommend it to those who want to have a good sleep!

Sleep apnea test -
After reading my sleep apnea report, my doctor immediately confirmed that by putting me in a sleep lab for my later anesthesia delivery. Belun® 's sleep apnea test gave me peace of mind.

Belun® Ring -
I rely on Belun® Ring which gives me a more comprehensive picture of my health, as it measures stress level via the automatic nervous system response and analyze my data using an AI platform, not yet available in other brands. I will recommend it to anyone who wants better health.
