CHOICEMMEDBlack Finger Pulse Oximeter - Blood Oxygen Saturation Monitor Great as SPO2 Pulse Oximeter - Portable Oxygen Sensor with Included Batteries - O2 Saturation Monitor with Carry Pouch

Is as described, works well. A good addition to the medical cabinet.

It was so accurate and easy to use.I had purchased it in September of 2022. Today, it stopped giving a reading, so I put fresh AAA batteries in and it would flash as though it was going to provide a reading and it went black-no reading. We tried it several times.Update: we tried different batteries and it began to work fine again! Although the other batteries were new, apparently the device did not like that brand.

Ease of use and readability of the display is key to the success of this product. Purchased it for my 83 year old father who had no problems I stamly picking it up and using it to track his oxygen levels. The ability for him to self track such critical stats with a unit that is small enough to always be available is a godsend. The fact that neither his cardiologist or oxygen supply company would overlook such an important tool is unforgivable in my opinion. I highly recommend this product for its ease of use, portability and extremely affordable price

This is a real oximeter like the doctor uses, and so easy to use and affordable!

Several doctors, quoted in assorted reputable magazines and newspapers, have recommended that people check their blood oxygen level at home, because COVID may affect that level long before people feel sick enough to go to a hospital. Early treatment is vital. Although this oximeter is not the medical version used in doctors' offices (it's intended for things like sports, for example hiking up a mountain) it provides a handy baseline. You can watch for trends, rather than specific numbers. If your blood oxygen goes down, call your doctor. If it stays stable, no worries. I use this along with a blood pressure monitor, and the pulse rate shown on both are practically identical, which makes me pretty confident in using this. It comes with a cute padded container and a lanyard. The lanyard looks as if it will break at any moment, so I'm not using that. The instruction manual is in tiny print. I needed a magnifying glass to read it. Worse, the batteries must be placed according to a white-on-white logo in the battery compartment...I needed a LIGHTED magnifying glass to see that! But it works pretty fast. Note: you should use this on the middle finger of your dominant hand for the best reading, not your index finger.

This product works well as described. The results are visible in a few seconds. I tested this unit and another one from a different manufacturer simultaneously and they gave identical results, which suggests they are probably reasonably accurate. I can read the results outside even in bright daylight, unlike another unit I purchased. This is important to me because I check pulse-ox while exercising outdoors. It also comes with batteries and a nice case.

We have several oximeters to use around the house. It is very accurate & easy to read.

We were really looking forward to receiving this item to assist with monitoring my husband's oxygen levels after being diagnosed with pneumonia. While we can understand that there was a delay in shipping, the item was unfortunately delivered in nonoptimal condition as it did not report a realistic oxygen level. Above is a photo of my husbands levels less than 2 hours of receipt of the pulse oximeter. As my husband was showing no signs of distress, he was upright and able to talk without being short of breath, I have a hard time believing his level was truly 33%. To make matters worse the item is nonreturnable. I guess we will be heading to the store in an attempt to purchase one so that we can try it before we buy it. The item was easy to use and the display was clear and easy to read as well. If only it were accurate.
