Pulse Oximeter Fingertip for Home Use: FSA Eligible Oxygen Monitor - Enhanced Spo2 Blood Oxygen Monitor with Bold Dual Direction Readings - Wide Applicable o2 pulse oximeter finger for ages 3-80

Works well enough. Compared it to other devices, including an apple watch and it read accurately on both metrics. Sometimes it can't read with my nails so I use a shorter nail or adjust my finger (when that happens it's obvious because it shows lines, not a reading). It's been incredibly helpful. When I crashed and was stuck on the floor I was at one point able to get it out, on and angle my phone recording at it. When I passed out on my side it kept reading even though my hand wasn't flat like usual, my hand was angled but it was straight on my finger. Thankfully it's not too heavy and didn't fall or something. I'm grateful for the readings. At first my cardiologist recommended this to watch my pulse but the O2 reading has been surprisingly helpful, none of my doctors had suspected that was a factor since it's been good during visits. Butttt I haven't fainted in the office while being monitored lol. I got lucky my phone got so much video. Is it the fanciest, coolest looking model? No. Is it affordable? Yes. Is it worth it? YES! Worst case scenario, you're still searching for an undiagnosed condition and find you don't have a certain issue.

Necessary item, good price, effective, its screen is easy to read at sight, good brightness and easy to use, you just put it on your finger, turn it on and in seconds you get your oxygen level

I bought Pulse Oximeter (COOCEER), but it did not work. I thought the problem was due to shipping and handling. I planned to return it. But, before I took the action of returning it, I received a message from Diona, a professional assistant of AILE Medical LLC that manufacturers the product. The message asked me if I had any problem with the production. My answer was "yes, I had a problem." Immediately, I received a new Pulse Oximeter, which works great as being very accurate. My point here is that it is good to have honest and professional people helping you solving your problem. I highly recommend this product. Thank you.

Purchased this item to monitor oxygen levels. Very accurate readings but helps if you warm the finger first. Not as fast or accurate as hospital version, which is why I gave it a 4star rating.

This works well. Just put in a couple triple A batteries and you're good to go. It's easy to read and seems to be very accurate. It has a strap that attaches to it, so it's easy to keep track of. Very easy to use.

Won’t turn on at all. Yes, I put fresh batteries in.

I bought this pulse oximeter half a year ago, and it still works well—great price for what it does. It's super easy to use, and the display has large numbers and is bright and easy to read. Looks pretty accurate and much quicker than others I have used before.
