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.

Works like advertising and right price.

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.

Used less than 5x, worked great, but after that, a big flop. It turns on but fails to read Heart rate or pulse ox. Tried different fingers. Removed batteries just in case it needed a reset. Turned off and on. Waited for the reading that never came. After a long wait, it turns itself off. Lens is clean. Frustrating when you buy a product and expect it to work, and pffft! What gives!?? Hope this helps.

Agrees with my phone app, and doctors office. easy to use/read. good price

Excellent product, durable, easy to use accurate, and 1/3 cost of brands found at local drugstore and medical equipment stores

Works as any other pulse ox does. Claimed the batteries are included but did not come with batteries.
