Bests & Worsts Reviews from Amazon

The first reading this morning showed I had blood oxygenation of 99% - with a pulse of 40! Confident that I am NOT Michael Jordan, I tried a multi-device comparison. In this, my blood pressure tester showed a pulse of 76, my cheap pink meter showed a pulse of 74, and the SantaMedical showed my pulse at 56. The BP tester was on my left arm, the two finger meters on my right hand. All readings were taken simultaneously. The BP device, the pink finger meter, and my subjective experience were in accordance with each other. The SantaMedical was consistently an outlier. I have no way to evaluate whether the PI readings are accurate or not, but I note they ranged from 1.5 to 5.0 within 10 minutes without any external variables changing. Beautiful display. Crazy data. Going back! Feb 2, 2021 These vendors are incredibly - BAD. They must have sent me at least eight emails asking me to delete this review of their defective junk. Several plead that it is a family business and bad reviews hurt, implying that I am against family and hurting children because I've taken the time to write an honest review. In at least three of their emails to me, they have offered to bribe me. The first bribe offer was for $30. In the second or third, they upped their bribe offer to $35. This, on a product that costs less than $20. The vendors include links to facilitate deleting and or modifying my 1 star review. (At this point it would be a negative 5 star rating if I could give that instead of a +1 star.) I told them that if they sent me a meter that gave accurate data, that I'd test it and update this review - but no! Their response was to tell me that because of Covid-19 they COULDN'T sent me a replacement meter. Covid-19 doesn't, however, seem to diminish their efforts to sell more meters right here, today! Shame on them.
