Bill was very knowledgeable and gave me all the information that I needed to rectify my problem. I felt comfortable sharing the details of my problem and he seemed to be very empathetic to my situation. He gave me step-by-step directions to allow me to get the information I needed over to the DMV and the courts. I Would highly recommend anyone in a similar situation to speak to Bill in the future.

Great customer service and quick quality assistance. I would recommend this to everyone!

Your Ohio representative Samantha Bowman did a great job of getting me enrolled..she set up an appointment for my local installer and even gave me a call back the same day to verify my schedule appointment for next week.. She was not only efficient but friendly as well.. I could hear her smiling through the phone .. GIVE THAT GIRL A RAISE !! 😊🙌🏼

Tawana assisted with appointment setup. Very easyand she answered all of my questions..

This is the worst company I have ever interacted with, first they installed the system incorrectly the truck wouldn't even start to let us leave the shop and all the guy did was twist some wires around. 4 days later we had to have someone else completely rewire it because it kept telling me to turn off the vehicle and said I violated and showed negative days, but when I took it in it showed I did nothing wrong. The first place was supposed to refund us our installation fee since I had to pay someone else to reinstall it and never did. Only a month later I have had to take off work four times to have it reset because it keeps going negative and now they want to charge me 100's to have it taken out! Save your money and go with smartstart this company is a complete joke!

These guys John and Matt at Guardian Interlock are the best. Always there to help out and guide you to the right answers. The mobile service is such a great idea and the experiences I've had with it are phenomenal. I had to have a machine swap to another vehicle. Originally was going to happen at my house however the registry took a lot more time than I expected. So I cancelled service to my house, talk to John and he drove all the way to the Braintree registry from Somerville in traffic to be there for me for my machine swap. If it wasn't for the mobile service the swap would never had happened for me. They are the best !!! Thank you so much Matt and John.

Jessica was very helpful and after a bad experience with another provider I am confident this will be better.
