Not accurate from a few minute duel and multiple
This is pretty and the "on hold" music played while you wait for the results is quite relaxing but there is a definite discrepancy with the reading within a 3-5 min period of taking a another reading. I sadly cannot accurately determine what the true reading is. It is so far and off the prior reading in a short (few mins to calibrate) of the one taken prior. I even took with me to a Dr appt and they confirmed it was too inconsistent to regard as a an accurate use of measure. I paid $10 on a Black Friday sale, so I guess you get what you pay for.
