Exelente lo disfrutaré mucho

Bought for my dad who has pulminary fibrosis. He loves it for measuring his oxygen.

Does exactly what it says it should.

Due to a recent surgery, the hospital staff was checking oxygen multiple times a day. Sometimes I could not see the results they got. So, I found this device on Amazon. It works as described. It is easy to use. The small booklet included helpful information about getting an accurate reading. At least one person on the hospital physical therapy staff also had this exact device. That is a recommendation beyond my own.

I recently found out that I have a lung problem. So I need to check my oxygen level 3 times a day. I can make sure that my level is where it should be. Works great.

Easy to read and understand display for oxygen and heart rate

Great product!

Easy to use and read.

Easy to use and seems accurate. Helpful to keep track of oxygen level.
