Our Review/Thoughts

The oxygen saturation reading is in large digits

ngineer for over 30 years, I'm impressed with the rugged reliability apparent in this product

It takes 5-10 seconds to give O2 level and pulse rate

That unit reads the same as or within 1 point of our original unit

I recomend this to anyone who is worried about the amount of Oxygen in their blood

Then it shuts off automatically once removed
