Q: Always reads 99 SpO2. Either I'm in excellent health, or it's not working

yavkv You are right! It does not work. I check it with my doctor against professional oximeter. When normal unit shows 96-97%, which is correct, this crap shows either 99% or 90-91% depending on my finger position inside the clip. Do not buy this device!
