The price is not very expensive and I like it. I like the interface and the design. It is good because it is type C. It seems to come out well compared to a conventional oxygen-saturated meter that didn't make much difference in the hospital.. Sometimes the oxygen level is 1-2 low.
The most wanted function, the alarm sound is big, so good. I will write well ^ ^
I don't know how to find additional probe purchases ..
