Fingertip Pulse Oximeter for Oxygen Level and Pulse Rate, Batteries and Lanyard Included

I have had numerous oximeter. This is the least accurate I have ever tried. My other models say 97 percent O2. The doctor's office says 99 percent. This model keeps saying 93 and then it starts beeping to alert you. It also reads very low for HR. heart rate compared to many other models.

You get roughly what you pay for. You can tell this product to beep each time it detects a heart beat. The beep can be made loud enough to hear easily. This is a nice feature if one is trying to monitor for skipped heart beats. But this product will miss or double heart beats if you are moving. It seems to be more of a problem with this product than its competitors. You will need to be very still, so you can not use this device as a tool to augment your workouts. Some other pulse oximeters support bluetooth. This one does not. It's something to consider before buying. Otherwise this produce seems fine.

The bananas are an inferior brand, they are often rotten and black halfway through to the end of it. I won't even feed this to my dog and my dog eats human grade food.

On the outside of the box it says for aviation and athletics only. No where in the description does it say that.. I almost went to the emergency room because the rereading s were so poor. Very poor product for medical use Retired Nurse

this is the best one I've ever used. be prepared to buy triple AAA batteries for it tho. I hate trying to use medical equipment when really needed that have dead batteries 'included'.

This is pretty accurate and well worth the price. I won't bore everyone with the details, but my brother was sent home from a hospital with 91 % oxygen and told he had a lung infection and given antibiotics. I got this and his oxygen level went to 83, so we took him to a different hospital that found blood clots in his lungs. So this basically saved his life. If you're having oxygen concerns, please get this or another one and keep an eye on it and go to the hospital immediately if it's low.

works great, i keep watch of my oxygen due to lung illness

everything was fine except the readout. extremely inaccurate. scared me to death almost when I read very low oxygen on the bottom.

This oximeter works very well. Great value. Very well packed. Promptly delivered. Thank you.

This oximeter doesn't work!
