Accurate and easy to use.
This little bad boy is a gem for the price. I have a stethoscope and sphygmomanometer (sp??)  and have taken it manually and with this unit, and I am impressed. Great for people with bad vision and the voice telling you the results is cool. Granted, there is a thick Asian accent, but easily understood. I would recommend and have recommended to friends !
