The info it collects is helpful, except it only retains part of the data collected from each test. It would be far more useful for me if the whole chart was stored and shareable the same way it’s collected. Also, if I use it 3X in a row, sitting in the same chair, same position, I get 3 very different measurements. Not sure why. So it’s not very useful for me now. If I knew this, I would not have paid for a whole year.
