Fingertip Pulse Oximeter Blood Oxygen Saturation Monitor with Lanyard Carrying Case and Batteried Yonker YK-82 - Blue

I haven't used product more than 3 months. Product is broken already...not a good product.

I love it

I needed to know my oxygen level for my lunges witch also shows what the brain receives to protect me from strokes and heart attacks. This is an excellent meter to buy.

I returned the device for two reasons. First, it did not provide accurate results for me. As I wore it on my finger, the pulse reading dropped 20 beats per minute from the initial number, then increased to approximately the original number. Possibly this was because I have an irregular heartbeat, but a medical device should be able to deal with this. There was never an issue with a medical device when my heartbeat was measured in the past. Second, the battery case cover came off when I was not trying to remove it and was difficult to get back on properly. I am giving the product two stars rather than one, in case my irregular heartbeat contributed to the problem with the reading.

Worked once. Then didn’t work again. Promptly returned
