I had a hard time getting in to get my system installed. I got into the shop (in Tampa, Fl) and a tech (I think) named Tony was a huge help. I haven't had any issues and my device works great. He covered every possible scenario. Thanks Guardian amd Tony!

Prior to calling Guardian, I had no idea what to expect because I had not done any research. I had only heard stories from others' experiences about the interlock companies they had used. I was quickly relieved to learn the staff was knowledgeable, professional and friendly. It was a quick and painless process and I feel the staff went above and beyond to make sure I received exemplary customer service. Further, the pricing was fair and reasonable. I would recommend Guardian to anyone in need of the interlock service.
