Quoted me the wrong price Quoted me the wrong price. Set me up with two wrong appointments, one being three thousand miles from me. But, was a decent price. Edit: From 2 stars to 5. Company reached out after having a few problems with them and gave me a great discount for wasting my time and misquoting prices. Everything has been resolved, couldn't be happier.

Honest and good customer service Honest and good customer service. He has always been positive and adapted to every time change I had. Have really enjoyed knowing him, he does his job very well.

I would recommend Guardian interlock… I would recommend Guardian interlock based on my initial customer service experience. Tawana went above and beyond with helping me by answering all of my questions and concerns regarding payments, fees, installation etc.. I’m new to this situation and requirement of the state but Tawana (with ease) set up my account and booked installation on two separate vehicles on the date that worked best for me. She was a pleasure to have been helped by and I hope my experience with this company continues to be seamless as well. Thanks Tawna!

Tawana was great Tawana was great, and I would highly recommend her to help anybody who doesn’t understand the system

Mickey Mouse Design This device can’t tell the difference between food & alcohol.... being charged for an innocent violation up front is ridiculous... programming & design of the product is Mickey Mouse. Need to hire some real engineers instead of some back yard wanta be engineer. Driving & using this device continuously during a route presents a driving hazard & safe driving wasn’t a priority.
