As a nurse, I know how these things work, how they’re supposed to react to drops and rises in an O2 saturation level. This one, at times, can be slow to react to drops in O2 sats. We’ve compared it to the "full on” Hospital model. It did "catch up” with the drop and subsequent rise of the "sat”, but shorter "dips” could POSSIBLY be missed due to the "hang-time” in reading. Meaning, if someone drops for 2minutes or Longer, this will catch it, but of that 2+min, it will catch about a minute. So…

This meter is easy to use and seems to be reasonably accurate, though I have no good way to tell for sure. The display is small, but very nice, and reorients as you reposition it - nice feature.My only niggling complaints:1) It starts up and displays 96% or 95% for a few seconds before it shows you the real reading, so you have to ignore the first few seconds of readings (it seems to take at least 30-60 seconds to really settle in on a "good" measurement number, but it's passable after 5-10…

Half the time it doesn't really read right. Different readings on different fingers, like, vastly different. If I were in a situation where I needed to check this with urgency, I would not want to be fiddling around to get a reading. That said, the price is good and it gets me the info I need. sometimes :)

Great device but needs a little better explanation on some of the display readings. I would buy it again if i needed another

Screen stopped working and it hardly turns on. Sometimes it’ll randomly beep when you try to use it but other times it seems as if the batteries are dead. I’ve replaced the batteries and it still doesn’t work:/

I bought this, took it out of the box, inserted two batteries and ready to go. Had a doctor appointment the next day. Took it with me to check accuracy and it was exactly the same as the doctor's big machine. Instructions are a bit hard to read, but you really don't need them.

Good way to monitor your blood oxygen number from home. The print on the instructions is very small and faint, but it’s pretty self explanatory on how it works. Very accurate as it gives me the same numbers that I get at my pulmonologists office.

We got this in case one of us got covid - being able to monitor blood oxygen level is critical in deciding whether to go the hospital, or not. This unit is a great value! Accurate, and very easy to read at any angle on account of it's rotating display. As a bonus, you get the pulse rate and perfusion index on the same screen. I'm very happy with this purchase, great little device. Every household should have one!

This is the same one my home nurse and my doctor uses. When i first got it i compared readings of theirs vs mine to make sure and they matched. Highly recommend. Also durable, I can't tell you how many times I've dropped it with no problems. The batteries pop out but otherwise intact.

Good quality and reasonably priced. Used along with automatic BP cuff and thermometer to monitor my health. Accurate when compared to Dr's Office model.Only drawbacks are screen numbers are small and too sensitive to motion changing viwe horizontal to vertical.

Wow/-/easy to use pulse ox. monitor that is not tight and doesn’t pinch at all.This device does just what it says:Pulse rate bpmPulse oxPI%heart rate "waves”Btw I did not know what PI % was before purchasing this. However, now I do⤵️Perfusion Index or PI % is—the ratio of the pulsatile blood flow to the non-pulsatile static blood flow in a patient's peripheral tissue (such as finger tip, toe, or ear lobe).—an indication of the pulse strength at the sensor site.The PI's values range from 0.02%…

I love this oximeter it is easy to use and comes with batteries and the wrist band is an extra plus.The only thing I wasn't too happy about is the monitor keeps going and adjusting and does not stop for a set reading like a thermometer would do. Other than that it's worth the buy.I will say make sure you read or search the pulse rates for age range. I purchased to keep track of my 4yo with asthma oxygen level. It's worth the buy and I'd reccomend.I googled the 3 different readings and the pulse

Honestly I wasn't expecting much, but I was totally wrong! This thing is awesome.For the price and makes it even better.Really easy to read. 5 stars for me.

It was easy to setup, just pop the batteries in and go. I found it just as easy to use as the ones in a hospital and the screen rotation was especially nice. It seemed as accurate as the ones in the hospital. I've got a cold right now, thus the 98 instead of 99 or 100. Pulse was accurate. The contrast of the digital display is crisp and easy to read. You really can't beat this for price and accuracy!

I needed a monitor while my father was on home hospice care. Worked perfectly. Same accuracy as the professional ones and easy to read. Simple to use. Only thing battery life doesn’t last.

I should start by saying I like this sensor a lot. it helped me while being sick. As far as accuracy I think it's very close to medical grade as my numbers at the hospital were very close to this +or- 1. I also like the fact the display orients to the angle you are viewing (very useful ) buy with confidence well worth it. very easy to use
