I bought this pulse oximeter for my father, who has COPD, and it’s been a lifesaver. The readings are fast, and the accuracy is comparable to what we see at the doctor’s office. It's comforting to have such a reliable device at home, especially when monitoring oxygen levels is so important.

This pulse oximeter is very straightforward. My elderly mother has no trouble using it by herself, and the screen is large enough for her to read the numbers clearly. It’s been a great help in keeping track of her health.

As someone with asthma, I carry this oximeter with me everywhere. It’s small, lightweight, and comes with a protective case. I’ve used it multiple times when I felt short of breath, and it gives me peace of mind knowing I can check my oxygen levels anytime.

I use this oximeter for my patients as a healthcare professional, and it’s been consistently reliable. The results are on par with more expensive devices we use at the clinic. It's easy to sanitize between uses and offers quick readings, even with patients who have low perfusion.
