What Our Customers Are Saying?
"“ It's a terrific device and worth the price to me, I have a CPAP machine, the wellue vibration alert is adjustable in strength, relatively quiet and gently wakes me.The ring form factor and vibration alert appears to be unique in the marketplace for now. ”
“ This was recommended by our Dr.I have sleep apnea and I didn't want to wear one of those masks as I felt as if I was drowning so we purchased the wellue sleep oxygen monitor. It goes on a finger and it will vibrate and wake you when you are not breathing—so works great.“
