FL-350 Pulse Oximeter with Carrying Case & Batteries & Lanyard, Black

nice and easy to use

Compared it to the one at my doctor’s office and it was about the same. Works well and has lasted at least a year so far.

An excellent way to monitor oxygen and heart rate. I carry mine with me.

I need one for my mom!! Easy to use and reliable!!

I like the new pulse ox because the numbers are also large enough that my patients can see them .

I bought this a month into the quarantine in case i ended up needing to check my oxygen due to having asthma and the scare of getting sick i wanted this on me to help me see how much oxygen i am getting.It turned out to help me so much! I unfortunately and oddly got a pneumonia during the viral outbreak. I would be short of breath and luckily had this pulse ox to tell me how much oxygen was and keep me out of the emergency room. It’s a must have for the family! Especially anyone with any lung conditions or problems getting oxygen.

Works well for heart rate and oxy, update speed seems good and oxy levels seem like they could be accurate. Powers on and the mode can be changed with only one button. This simplicity makes a difference. Unit isn't large either. Some casual research has shown that it works as well as more expensive units.I held my breath and tested, very interesting exercise.

Perfect.
