The rolling retest does not give me enough time to find a place to pull over and respond. I keep getting "abort" messages. This feature is very dangerous and could lead to serious accidents. I have to take back roads to get around because traveling on the highway is too dangerous.

Dear Stephen, We are sorry that you are having trouble with the rolling retest and abort issues. We have asked the State Office to contact you directly to address your concerns. Thank you for the feedback.
Very positive, encouraging & personable rapport.

Carolina was very friendly and helpful, I felt like she was personally invested in making sure I would have everything I needed to be authorized before my appointment.

So I shopped around for a few days for the best "deal" on interlock devices. And by "deal" I mean that I was looking for a combination of customer service, speed of install, equipment warranty/reliability, and of course...cost. Guardian was the 4th provider I contacted, and the search stopped there. Melissa at Guardian was so helpful, courteous, and did so with a very pleasant, upbeat demeanor that I found refreshing. I actually called 3 other services first because of how they were listed on Google, but I'm happy that I didn't go with the first few. I'm very pleased with my decision to use Guardian, and will recommend anyone else the same.
