Review on Track Your Oxygen Levels And Heart Rate With IProven Fingertip Pulse Oximeter – Includes Battery, Case, And Lanyard In Blue by Steve Arnold
Not sure I trust it. Here's why:
Packed in a cardboard box + mailed in a brown paper envelope + ignored delivery instructions + hours of rain before I could get it = soaked device that's acting wonky. Is there something inherently wrong with the device, or did it get ruined by getting rained on through two layers of paper? I'm thinking the device was probably OK before the packaging and delivery failures, but I can't be sure.
- This little thing is truly awesome ! Gives a perfect reading everytime! Highly recommend! Thank you !
- May require frequent calibration
