Vibeat WearO2 Bluetooth Pulse Oximeter - Continuous Blood Oxygen & Heart Rate Monitor with Free App, Wearable Finger Oxygen Sensor for Fitness, Sleep & Health Tracking - FSA/HSA Eligible - Perfect for Athletes, Pilots & High-Altitude Travelers

Wonderful product! So very very helpful! I have asthma and sleep apnea, and I often wonder just how my heart and lungs are functioning during the day.Now I know every second. This WearO2 Pulse Oximeter was my answer. Comfy to wear, very Accurate, easy to use. VERY IMPORTANT… My $30 finger tip oximeters often do not work in the cooler weather because my fingers get too cold. I have not had this problem with these Vibeat products.I bought this daytime oxygen and heart monitor because it works very similar to their nighttime Wellue Oxygen Sleep ring… which I bought over 2 years ago. Both devices have VIBRATING alerts when your oxygen saturation drops too low. It’s customizable so you can set your own oxygen alert levels. The Daytime or Nighttime devices VIBRATE when your oxygen saturation drops too low.While this Oximeter wearable ring is not classified as a medical device, for me it is a wonderful adjunct and gives me great info that I can share with my physicians.I’m excited to start using this Daytime monitor because I’ve used my Wellue Oxygen Sleep Ring every night for over 2 years, and it’s wonderful… accurate and reliable. Two and a half years ago I didn’t even know these devices existed. I found it searching on Amazon for something to monitor my nighttime oxygen.Both devices monitor oxygen saturation AND pulse. Truly amazing!!! My new sleep apnea doc recommends the sleep ring to all her patients. When I see her next, I definitely will show her this new daytime device. It has a longer runtime than the nighttime sleep ring.Both devices let me and my docs know if my oxygen and cpap and asthma therapy are working like they should or if they need tweaking.It used to be very stressful going to sleep at night and wondering “what if my oxygen goes too low and I don’t wake up to breathe?” I no longer stress and worry about going to sleep because of the vibrating alerts from the ring.Both the nighttime sleep ring and this new daytime device make me feel much safer. The devices closely monitor my oxygen saturation and pulse rate and alert me when my oxygen is too low.HIGHLY recommend, especially if you have (or think you have) low oxygen, asthma, or sleep apnea.Ps… I did NOT have sleep apnea when I started to use the Sleep Ring 2 years ago. But a year ago after a serious surgery, the oxygen and pulse data from these devices helped my doctor determine that further sleep tests were immediately needed. And sure enough, the sleep tests showed my low nighttime oxygen levels had worsened and become sleep apnea.I’m a real person, I bought both these devices, and I was not paid to write this review. I buy tons of stuff from Amazon and rarely write reviews. But when I come across a truly wonderful product, I like to share the news.I am very thankful for these wonderful devices which help me monitor my oxygen and heart rate every day. I know they are not live-saving devices, but for me, they are close to it.
