I have tried Lifesafer interlock. It’s so difficult to start, I live in CA so I have a number of approved interlock devices, more than most states, so I won’t list them. LiifeSafer is the vibrating/humming. Can people please recommend which interlock devices they had experiences with and how easy of difficult it was to start? I will need this for a year, and need to find the easiest to use regardless the price. Any help is much appreciated.
