Fingertip Pulse Oximeter, Blood Oxygen Saturation Monitor (SpO2) with Pulse Rate Measurements and Pulse Bar Graph, Portable Digital Reading LED Display, Lanyard Included

I was surprised by how well this little device worked. It's super easy to use and the readings are surprisingly accurate. The display is bright and easy to read, and the pulse bar graph feature is really helpful. I was a bit skeptical at first, but after watching a tutorial online, I got consistent and accurate readings. It's not the most durable thing, but for the price, it's a great value.

Before you use this, I would suggest you find an instructional video online and watch it. This was my first time using a fingertip pulse oximeter and the instructions that come with this one are lacking. I was getting varied and inaccurate (very low) readings before I watched the video. There are several things that can impact the reading including how you hold your hand. The video said wearing nail polish can also affect the reading. It didn’t seem to impact mine but I usually only wear one coat of a sheer light pink polish. Once I watched the video and held my hand properly the readings were more stable and accurate making this a very handy device. I also wear an Apple Watch and the readings matched those of my watch which I think are pretty accurate.Please note in the description that this requires 2 AAA batteries that are not included. With so many items made to be rechargeable now, it would be nice if this was and did not need batteries. If you don’t have AAA on hand, you’ll need to be sure to order those as well.

This pulse oximeter is great! It's really easy to use and the display is clear and bright, I love that it comes with a lanyard too. I was a little worried about the accuracy at first, but after watching a quick video on how to use it properly the readings were much better. The only thing I don't like is that it uses AAA batteries, I wish it was rechargeable, but it's a minor complaint. Overall, this is a great product, I'd can recommend it to anyone looking for a reliable and affordable pulse oximeter

I've always wanted one of these pulse oximeter since I seen them used at the N.I.C.U. and I just always assumed these were some very expensive pieces of medical equipment. Imagine my surprise when I saw this product and realized it was below $20. I ordered it immediately with the thoughts that it must be a very cheap gimmick. I was wrong. The Pulse oximeter takes 2 AAA batteries. It has a very bright LCD so that everything is readable and all of the numbers and graphs are at a level of contrast the it's all readable. In fact, I was very surprised at how much they are able to fit on the tiny screen. The screen shows your heart rate at BPM (beats per minute), it shows your oxygen saturation percentage, and then it also shows a plethysmograph number but I don't really understand what it is or what it means. It's something to do with blood pressure differences but I won't pretend I know. It also shows two different graphs, one of which I believe is a graph of your heart best.It's very simple to use. It literally consists of squeezing one side so it opens up and then sticking a finger all the way in and it does all of the rest. Amazing little piece of equipment that everyone should have in their medical cabinet.

I recently purchased this product and have been quite impressed with its accuracy and portability. The LED display is clear and easy to read, providing me with quick and reliable measurements of my blood oxygen saturation levels and pulse rate. The lanyard included makes it convenient to carry around, and I appreciate the pulse bar graph feature that gives a visual representation of my pulse. Overall, a great tool for monitoring my health on the go.

I really wanted to like this. I needed something to keep track of my pulse (I don't wear a tracking watch), but this gives questionable at times.I didn't wear nail polish. I position my hand properly. Even so, this will give results in both the O2 and pulse rate that very significantly over 10 seconds or so. It will start out 97% oxygen, then go down into the 80s, then come back up to the low 90s. Similar things happen with the pulse rate also.So either my oxygen saturation and pulse are varying widely in a short amount of time or this isn't as accurate as I'd want it to be.Some uses, it works fine. But it needs to work properly all the time.

I was a little hesitant ordering this pulse oximeter because I was concerned, based on the price, that the quality would be questionable. I was pleasantly surprised to receive a very well-made product. The materials are sturdy and feel very durable. It does require two AAA batteries which are not included, but simple to put in.The accuracy is on point and matches those of my Apple Watch readings. The results are in color and simple to decipher. The spring that controls the opening and closing of the device is strong. My only issue is that I’ve been unable to attach the lanyard. There’s nothing in the directions to explain it and there’s nothing blatantly obvious that allows you to attach the lanyard. Otherwise, this is a very great good quality products that provides you with accurate readings. A good unit to have on hand to help you monitor your health. I would definitely order this again as well as recommend it.

Pulse oximeter gives quick and accurate results. The display makes it very easy to read as well. I use this to check my pulse after & before workouts. Requires AAA batteries, I thought it would be rechargeable.
