Melissa with Guardian is A-M-A-Z-I-N-G!
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.
