Upon making initial call to guardian for install of interlock system the experience was pleasant. Representative Sarah was amazing and very helpful. Glad we chose Guardian for this service.

I arrived on time and Steve was able to help me with the install. He was very nice, polite and knowledgeable about the product, installing the piece of equipment and training me on how to use it. Guardian Interlock is a top company that offers great customer service. This is how customers should be treated.
