Negative Positive
Title: Piece of junk!
Review: The numbers this shows are all calculated when you input your information. So it has nothing to do with holding it at all. There are numerous sites online that will give you the same info for free. This gave me the same readings if I was standing holding it at 90 degrees or laying down in the bed or if I just put the tips of my fingers on it. Doesn't matter. Save your money and just use an online site.
