Review: Easy to Use and Accurate - This is a basic oximeter which comes with batteries, a nice case and a lanyard. It appears to be quite accurate and was a good price.
Review: UPDATED: Still going strong 2.5 yrs later! ... - UPDATE: Still using this several times a day, and it’s still going strong after over 2.5 years of use. I’ve owned several different pulse/ox devices over the years and I can say that this one is the best of the bunch. I actually came back to desertcart tonight to order a second one so that i’ll have a backup, especially since I’m doing a lot of travel these days, mostly long cruises of at least 21 days. It uses AAA batteries which are easy to find almost everywhere. And it’s not a battery ”hog” -- the first set if batteries lasted about 18 months of daily use, checking my numbers 2 or 3 times a day. AND it’s staying accurate. I’ve taken it to my doctor's office twice a year to compare with my doctor’s pulse/ox and it’s almost always exactly the same or at most 1-2 points lower than my doc’s. It’s still a 5-star item. Original review: This is a newer version of an AccuMed Pulse Oximeter I've been using for several years. It's accurate, easy to set up and use (just put in the batteries), and the lanyard and case make it easy to take along when I exercise or travel. I have severe emphysema, prone to CO2 retention, so it helps to keep tabs on O2 levels when I'm doing anything strenuous so I can take pre-emptive action (specific breathing techniques) before I run into trouble. There are a number of small oximeters on the market and they all operate on similar technology, so it comes down to the quality of the materials used and how it's put together. Some are really junk -- accuracy is whacky, the spring clip gives out, etc. This one is very good quality and built to last. I've been using it for several weeks, usually 2-3 times a day -- more if it's a heavy exercise day -- and I've seen no issues at all. This one's a keeper -- solid 5-stars for accuracy and quality.

## Features

- ACCURATE OXYGEN SATURATION AND PULSE RATE READINGS IN ONE DEVICE: The Fingertip Pulse Oximeter fits all finger sizes from kids above four years old to adults as it measures the level of oxygen in the blood and reads the pulse rate in just eight to ten seconds. It is crucial to use the device in a stationary position and not while in motion for precise readings.
- LOW POWER CONSUMPTION: Equipped with two AAA batteries, the oximeter automatically powers off when not in use and delivers up to 20 continuous hours of battery life.
- PORTABLE AND LIGHTWEIGHT: Weighing only 50 grams, every AccuMed oximeter comes in a convenient travel case that protects it from scratches when carried on its own or inside your gym bag or backpack. Attach the included lanyard to the case or directly to the oximeter for easy reach anytime.
- ROTATING, CRYSTAL CLEAR LED DISPLAY: Read your oxygen saturation level and pulse rate results with remarkable clarity in portrait or landscape formats with auto rotation that detects your hand movement in the CMS50D1 models.
- DESIGNED FOR HOME USE, EXERCISE OR TRAVEL: While the AccuMed Fingertip Pulse Oximeter is handy for detecting vital signs, it is not intended for medical use but rather for situations where you need to know your oxygen level before and after your workout or sports such as running, hiking or cycling, or while traveling in an aircraft.

### ⭐⭐⭐⭐⭐ Works easily and consistently
*by C***B on January 26, 2026*

It works as advertised. Our old one just took forever to register Mother’s oxygen level and heart rate (if at all)—even with new batteries, but this new one consistently reads both and actually works with painted nails! I also like that the display turns automatically.
