Pulse Oximeter Fingertip with Plethysmogra, So2 Oxygen Saturation Heart Rate Monitor, Portable OLED Display

I only gave it four stars in ease of use because the directions were printed in such small print that one practically needs a magnifying glass to read them. Also, the directions are very vague on exactly how to remove the back of the device for battery installation. I was afraid I would break it while figuring it out.Otherwise, I think it reads accurately and it very easy to use.I would buy it again and recommend buying it.

This pulse oximeter was a piece of cake to set up and use. Readings seem to be OK but I have no test equipment with which to calibrate it and assure its accuracy. Readings vary depending on activity level, which is exactly what I'd expect. It's continued to work fine for a couple weeks but it's too early to tell about longer term durability.

Has a good grip and more info than most other oxy meters I recommend this seller to all

Easy to use and accurate, I checked it at my Dr.s office.

Obviously it is easy to use but it has come in handy as my blood pressure is considered "soft" . My BP cuff will not always pick up my pressure so this has come in handy as a way to monitor my heart rate. My cardiologist suggested I get this type of device after a recent problem.

We took this to a mission trip. It was very helpful for general checkups. Easy to setup and use. The size it is convenient for overseas trip.
