"I had a very bad experience with Lifsavor/Guardian Interlock services. I called Smart Start and spoke with Itzel. She was very professional and polite. Not at all at Guardian. She went over the program in detail and answered all my questions in detail. It was very uplifting to talk with a positive sales rep after the degrading respect I received from the Guardian reps. Thank you so much for making this negative a positive for me! Tim "
