TrackAid Pulse Oximeter Fingertip Oxygen Saturation and Pulse Rate Monitor Upgraded Model

Absolute crap. Bought at the end of May and it completely stopped working in July.Accuracy is nonexistent. It will show 79% SpO2 and then randomly jump to 97%. Quite frequently, ALL of my patients would be at 97% despite our hospital-grade equipment saying otherwise. Heart rate would show too low or too high from actual rate.This thing drained batteries like nobody's business.Extremely slow.Now, it turns on and there's a red light but absolutely no reading.Save your money and buy from reputable brands.

Unfortunately this worked for 5 months using occasionally about one to 6 checks per month. I used it last 2 weeks ago and today it wouldn't turn on, I changed the batteries and same :(

I recently went back to hospice and as a nurse in field for many years this is by far the best pulse I have ever used!!! It is great when you can see the numbers and readings in the dark! Crystal clear and a great buy! I most likely will be buying a backup!

I haven’t had any problems except it can be a bit slow to read. It’s worth stating that it does beep somewhat loudly which may be undesirable for some.

Got this for the wife who is at a rehabilitation/therapy hospital. She can't see the Oximeter behind her on the wall. With this one I show here that her blood oxygen is fine. Then she relaxes. We also had fun passing it around the family and seeing the results. At this price I will order another ! Works great and is calibrated very close to the large one at the rehabilitation/therapy hospital. I could not be happier with this purchase.

Best micro pulse o2 I have ever owned. Great display for quick read. Got it for my personal jump bag and it’s perfect.

I didn't like it that it always gives a 99% O2 reading right away when I know for sure it should not be. After an exertion, my reading would usually be in the low 80s from past experience with other oxymeters, but when I put on this new one, it gives me the 99% reading right away. It really frustrates me because I know for sure it is not accurate.

This simple device measures all of the body activities advertised. Screen is bright and clear.
