My boyfriend is having major problems with this device. Miss blows are regular however he never misses a blow. He has had to return the machine 3 different times. He has already been thrown in jail for the machine reading 5 different readings in the matter of minutes, then released the next day because the charge was dismissed. He is facing 6 years and is working his butt off on doing everything right, yet these problems keep happening with this machine which could easily get him revoked at anytime. He does not drink anymore, he has followed all directions from Smart Start (what advise they say could be causing it) and still violations left and right. What should he do??? He is suppose to get it off in a month. It has been a year.
