  • good for dysautonomia
It works. I've had it for five years and it still works fine. I have POTS and have had to use this to check my HR during flair ups and it helped me get diagnosed and monitor treatment.

  • Easy to use.
Installed batteries and my oxygen level was 99% can’t get any better than that! Thank you, for this easy to use oxygen probe.

  • Works great
Works as intended, does not work for my 5 year old who’s finger is smaller. But works great for the rest of the family and we love it for a peace of mind when sick.

  • User friendly
The media could not be loaded. Easy and simple to use and great for the price. I recommend this to my patients to monitor their O2 and heart rate at home. Nurse approved!
