Mibest OLED Finger Pulse Oximeter

I purchased this one (mibest OLED Finger Pulse Oximeter) along with a second one by Fingertip Pulse Oximeter, so I could compare them to each other. Their readings were either the same or one digit different. The lanyard was a breeze to thread through the holes unlike the Fingertip Pulse Oximeter. Lastly, I used brand new AAA batteries instead of those that came with the package.

I bought this for a couple of reasons: 1. part of our COVID monitoring arsenal and 2. I’m an older competitive cyclist, triathlete and mountaineer. I climbed Kilimanjaro last year and while I was by far the most fit of the group climbing (not counting the local support “sherpas” that climb the mountain 4-6 times a year and don’t even notice the altitude!), I struggled the most at the very top, with a PO2 of 76%. I figured it might be interesting to see how my PO2 looked at normal altitudes during and after training, and to use during a Mt Shasta climb planned for this spring – that has been COVID-rescheduled until next spring.

The unit’s apparent accuracy (my wife is almost always at 98-99% and I’m typically at 96-97% was confirmed two weeks ago during a cardiac stress test I had done with a fellow athlete cardiologist. During the test we tested this unit against a similar unit used in the clinic. The two read exactly the same – until this one stopped taking readings. It seems this unit has a problem with sweaty hands. I cannot get it to read after a hard indoor cycling training session (Zwift, if anyone cares to know). Even wiping my hands with a cloth will not elicit it to give a reading.

In the end, this unit is fine for taking readings while sitting on the couch, but it is not proving to be particularly useful under exercise conditions. I don’t sweat excessively when I train, but even under modest sweating conditions, this unit just will not take a reading. We will probably end up buying another oximeter, if we can find one that works under exercise conditions.

If you just want to take a reading for medical purposes during normal people activities, this one will probably work well for you – it was shown to be accurate. However, if you want reading during or after exercise, you might look elsewhere.

This is a great oximeter. Very easy to read, even in broad daylight, and you can orient the display to face whatever direction you want it too. I like the case as well. Keeps it protected in my purse.

Item ordered on 23rd, received on 30th. Satisfied with delivery speed. However packing can be better as item was packed loosely in a big box, free to bounce freely inside might damage the electrical goods. Tried first time seems good quality product and hopefully will last. Product is as advertised.

Pretty good but not so acurate.

Excellent purchase! It is easy to work and even my elderly mom who has some memory loss can use it!
