I work in the medical field and have also had Covid twice, and I’m diagnosed with with Peripartum Cardiomyopathy (which is pregnancy induced heart failure; the only heart failure that you can recover from) so I fully aware of how pulse ox’s are supposed to work and can tell when they are faulty. I even did the “3 minute walk test” with this one and it didn’t miss a beat. My last one I tried for a while was faulty, would say my o2 was 90 when it definitely was not - you would know if you were at 90, trust me. I felt fine. So I’m giving this a 5 Star because it is accurate and durable at detecting your o2 even while in motion. Note: the best way to record your o2 is at rest. The physician that I work for has us do the 3 minute walk test with patients who’s o2 is in question, regularly.
