Due to two family members, I researched and later bought this item. It works great. The display is easy to read. My doctor told me and I had read that these products are three numbers off. So it's important to remember that if the oxygen says 92 it may be more like 89. I would definitely recommend this product.

While at my doctor's office, I asked my nurse if these were available. She said yes so I got one and they work great and alert me to any problems, I might encounter.

works as described

I purchased this brand because all of the positive reviews it received online. It works well and is very accurate. It's also easy to read and you can adjust the brightness if you're having difficulty reading it.

Light and easy to use. I carry this in my purse.

As a nurse whose husband has a serious lung disorder, I compared this pulse ox reading to the one in the hospital. The reading was the same. This item stays at my beside.

Just what you need to keep an eye on your oxygen level.

Used for keeping track of pulse

Use this all time in conjunction with my blood pressure machine.

It is easy to use and it os accurate. Has an automatic shutoff

I really like this oximeter, to the degree that I now own three of this exact same model, not because they break or stop working, but because I got tired of carrying one single unit around with me everywhere. I now have one for my night stand, one in the car, and an extra for my carry-on bag. My first original Innovo Deluxe iP900AP oximeter is still working great after four plus years constant use. The reasons I like this particular oximeter over other options is because it is rather accurate, it has a plethysmograph to show any irregularities with my heart beat, it displays the perfusion index, and it has a battery level indicator to tell you when the batteries are getting weak and your readings may be inaccurate. Most of the other brands don't have all of these attributes all in one unit, and the ones that do have are right at the same price. I can't say that any of the other oximeters are not as good as this one, but I've only used this one, and can only relay my experience and opinion for it specifically. I have read some of the other reviews to see that some people were having accuracy issues with theirs, or that customer service wasn't up to par. I can't speak to those problems. As I said, I can only attest to my own experience. I have never had to contact Innovo customer service, and the units I've purchased are all three dependable, accurate, and enduring. Therefore, I can say that I highly recommend this model from this manufacturer. And maybe my experience isn't too far off since the info page shows over 42,000 reviews with a 4.7 star rating. Good luck if you buy this product, and I hope you have the same positive results that I have had.I came back to add something that I hope might help some of the people who were complaining about poor accuracy with this unit. I have noticed on occasion that I would receive a questionable reading when I first turn the unit on, and that typically has to do with low temperature, either of my finger or the oximeter itself. What I have learned to do is wait one or two minutes before reading the oxygen level as this gives it a chance to calibrate better. I've watched my initial SpO2 reading of 91 quickly elevate to 98 or 99 after only a few seconds, not because my oxygen level suddenly changed, but because the oximeter had warmed up to acquire a more accurate reading. And during the wintertime, this condition is especially true. If you've been exposed to cold weather and your hands are icy, warm them up with warm water first before trying to get an oxygen reading. I hope this helps.

I don't think the perfusion rate is accurate but o don't really care about that

Reassuring.

I had another that would not read my finger. My friend sent me a link for this one and it works on my skinny fingers. The reading is accurate. Detects oxygen and heart rate. I take it on big mountain trips for readings at altitude.

it is good to see the blood flow on a graph if you have heart beat problems. saturation o2 is easy to read.

It arrived when they promised and works just as advertised.

Able to keep up with my oxygen levels now it is so easy.

We have used others but none had the ability to read carefully with an arthritic finger inserted. It's quick, comfortable and accurate (tested against another) as well as easy to read. What's not to like?

Sometimes it gives a crazy reading. Turn off and back on and then it seems to work well

Excellent price and fast delivery.
