WelluePulse Oximeter Fingertip Blood Oxygen Saturation Heart Rate Monitor with Batteries and Lanyard Bluetooth FS20F White

My odometer works great. It gives me my oxygen levels as well as my heart rate. Just stick your finger inside the odometer push button on and you see the results right away.

I use this often. Very durable as well as easy to use. Love these app as well as the accuracy it provides. If you have any lung issues, buy one! You will be glad you did.

Easy to use. Easy to read.

The instrument appears worth the low price. I have not be able to check all the software features. I just downloaded. the support software from Google.Read the warnings on its use regarding infr red light and wear time. I am not sure that these warnings are unique to this instrument and may apply to similar products.The product was ordered 3/12 with next day arrival mention the Amazon discription., however it was not received until 3/15.The product gives similar results but not exactly the same results of my old instrument, But my old instrument was about 5 years old. I am satisfied with my purchase. I will keep the instrument for general use but may look for something else due to my unique situation to measure over extended periods of time.

Works well. Would recommend

Good quality at a good price. Seems to work just fine! Yes I would buy it again!

Came with batteries and a strap. But, the pulse oximeter doesn't work consistently. My pulse read 91, 94, and 25 in three tries within 15 minutes. I had expected that the oxygen measurement would change with deep breathing, the way it does with the oximeter in the doctor's office. But, it did not. I'm returning this because I cannot trust the measurements.

Shipped super fast and works perfect
