"I wasn't entirely satisfied with how my Fitbit monitored my overnight blood oxygen, so I decided to invest in this finger-held blood ox meter. I was impressed by its modest price and easy usability. The data organization is amazing, though it takes some time to learn how to read the various graphs. Overall, I have experienced no problems."

"I find this pulse oximeter to be well-made and effective. It provides two clear readings: heart rate and blood oxygenation level, both of which are easy to read. The addition of a perfusion index (PI) is a nice touch, as it indicates if there's enough blood flow for accurate readings.

It provides very accurate readings compared to my other sensors and my watch, which takes a full 15 seconds to get a reading. The display is crystal clear, and while there are cheaper options, the quality of Innovo is worth the investment."

"After my COVID-19 test, I learned about the Pulse Oximeter. This device not only measures my oxygen levels but also tracks my heart rate. It prompted me to seek medical attention, leading to the discovery that I needed a pacemaker. I bought another one for my brother who needs to monitor his oxygen levels regularly, and I find this device to be a super-convenient way to check my vitals. The cool-blue color readout is much better than the alarming red from other brands. I’m proud to own this state-of-the-art device!"

The build is not as solid as the doctor's version, but for home use, this is perfect and reasonably priced."
