My mother needed a pulse ox for her asthma

Unfortunately, I lost it but it is accurate and consistent

Once realizing that I find this to be a great bargain

I don't use the case to store it though, because inside the case, it pushes the on button and drains the battery faster

Looked at the store and was surprised at how much it cost! i am happy with both the affordability and qualify of this product

y off but just 1% maybe 2% but you'll get that with these portable ones no matter what you buy I'd been quite sick recently and the nurse recommended I buy one of these
