Bests & Worsts Reviews from Amazon

I purchased this product to use during my shifts in an Emergency Department. I am a nurse and having this in my pocket saves me time. A full set of vitals is required on admission and discharge and often times we have to hunt down our departments portable SpO2 monitor (we only have 2 portables). We have gone to disposable sticker type monitors in each bay, but we have to charge the patient for them and they interfere with the patients activity when on. If I don't need a continuous reading this is perfect! So far, I have no cons for this product. It is at a great price point and i have tested it's reading against our monitor in our bays and they are identical. I will update after a few months use to attest to durability.
