    The ring is very comfortable. At first, it felt a bit strange, but after a few days, I didn’t even notice it anymore. It really helped me regulate my sleep and get better rest. I highly recommend it to everyone.

    This ring is a game changer and life changer. I got it for my 54th birthday. It made me aware that I might have sleep apnea, by showing me that I was having disturbances in my air while I slept. This information lead me to have a sleep study which did indeed say I had sleep apnea. It’s also making me aware of how important my sleep and my heart rate is. Having sleep apnea explains why I’ve had high heart rates at night.. my body was in distress from lack of air. I want to have a great cognitive future and having air while sleeping and getting the right amount of sleep is a great start.

    Nice device. Bought it for my wife because she did not like wearing the Apple Watch. It was not good at tracking steps, but then again that’s not one of its strengths. In terms of tracking sleep, and health patterns that’s where it shines. She had zero complaints about that and embraced it.
