Less than one star this is the most terrible company ever if you ever have to have an interlock device installed do not get intoxalock they will lie steal and cheat if they have your credit card number they will charge bogus fees and taxes to your card and you can't get it back their devices will leave you stranded in the middle of nowhere and their customer service is the worst if you can talk to somebody that speaks English they still won't help you this company literally lied to the DMV and said that I was not compliant when I was just to keep me on for longer how this company is legal I will never know but it is all a racket
