UPDATE- After I wrote this review, Scarlett from Guardian reached out to me, she took the time to explain in greater detail their process. Within a few weeks after that Ezra contacted me to follow up. Both Ezra and Scarlett went above and beyond to resolve and amend my complaint. I will be not be switching to another company. The Interlock Company in Omaha technician Chris is absolutely amazing and provides superior customer service. This review pertains to Guardian Interlocks call in customer service and lockout policy... 2 hour phone wait time on a Sunday to get a lockout code because my car battery went dead and the devices data was full. Representative said to call back this morning for a code because the code would only allow me enough time to drive to get to the place it gets calibrated. Had to arrange to get my son a ride to school, am late to a clients all because my car battery went dead. Takes hour of wait time to get through to customer service. I'm switching to Draeger tomorrow. Most terrible experience with this device and this company.

It's very easy to operate and glad I can take it out of my vehicle and take it inside but the warm up time takes a long time to be able to blow in it so I can start my vehicle. But other than that it's not bad.

Todo bien, solo que el aparato me lo dieron sin una base fija, y eso a hace que se vuelva un poco incómodo sobre todo al tiempo que pide muestra cuando uno está manejando.

It took six hours to get a callback from the automated system the time was 9 PM. UPDATE: I appreciate that guardian reached out. And also that they resolved my initial issue. I’m upping my 3 to a 4.
