My wife has been using this devise for over a year and it is fantastic! It has helped her keep her reading in check, even through her pregnancy. With out it I do not think she would have done so well! This company will continue to increase its revenues and profits every quarter, because once you use it you will never give it up! Buy and just put these shares away for a big pay out in the years to come! Buy and Hold.... Long on this one and don't worry about the market!
