Zacurate 500C Elite Fingertip Pulse Oximeter

Flawed from the Start – How this became the most popular Oximeter in Australia is beyond me. This is the third Oximeter I will be testing, and it has to be the worse for accuracy. I hopped off my cross trainer and sat for 5minutes, I then took these photos within one minute, that's about 5 seconds apart and as you can see my bpm varied from 67 to 118 which is impossible. This machine had one consistancy and that was the 02 level shown in all the photos as the same. I can assume from this that it is a misleading piece of junk that does nothing but plant confusion in the user. Get yourself a real Omron machine that gives you your blood pressure and your bpm and throw this in the garbage can!
