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.

Very disorganized process Very disorganized process, appointment not seen at shop, shop opened late after appointment. Equipment not received. Made to feel like lower than life for having to get one installed by staff and guardian rep not very clear on set up appointment. As soon as installed had to go right back to have recalibrated.

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!

Guardian failed to report compliance to the State Guardian failed to correctly report my compliance to the state and six years later I my license is being suspended by the state for non-compliance. However I had an IID for 6 months, paid Guardian every month, provided the contact information for the state. Now I have spend 2 days on hold, no one will answer or help me get records. Guardian has failed in their duty to report this info correctly to the state.
