"BEWARE" they are very nice when you're setting up the install & giving you pricing that once it's installed all goes up$$ My install was $40. More than quoted & took 6 days since the service center was waiting for them to send the unit, the first one was defective. I sent in my paperwork & check to PennDot only to get it back in the mail saying I'm not required to have the unit installed. Their "salesman" told me I was required to have this installed in my state. Nope! Intoxalock never sent the installation paperwork in either. I called them several times stating I have a letter that I don't need this but kept saying I need my state to send them a letter. When a state representative tells you to just remove it, that tells you this company is a scam. Decided to take it & get it removed so after spending over $800. For a 60 day suspension I'm not giving these crooks another dime.
