I wish I could give them 0/5 stars.
First of all, their website stated that "installation is free." When I showed up, after my customer account was created and my credit card number was put into their billing system, Hector then decided to tell me that I would have to pay the first month's fee of $82.00 and a WIRING FEE of $25.00! I went to multiple other locations for ignition interlock devices and NONE of them charged for wiring. And the hassle they put me through doesn't stop there.
I was going on vacation in 2 days so the whole "free install" statement made this place very attractive. But after I learned that I would have to pay over $100 to install it I told them that I couldn't pay that right now and that they need to take my information out of their system. Hector informed me that he did. Two days later as I'm driving up to Colorado for a week, I notice my bank account was lower than what I remembered. HECTOR CHARGED ME THE $82.00 AND THE $25.00 FEES THAT I WAS TOLD WERE NOT TAKEN OUT OF MY ACCOUNT. It took 4 days and 5 elongated phone calls with 3 different companies (one being my bank) to get my money back. But wait, there's more! :D
I got my interlock installed for $50 at another shop and I think I'm in the clear with Arizona Interlocks.... WRONG. I received emails from their third party billing company (yeah that's correct, it's as sketchy as it sounds) saying that Hector and his company installed my device that day and that I would be facing legal penalties because I never got my device serviced. So now my driving privileges are in jeopardy because of either Hector's lack of competence or his desire to screw people out of their money.
This company was such an appalling experience and if I even hear a stranger on the street mention that they're going to get an interlock installed by them, I will go out of my way to tell them not to. It's pitiful what Hector is running over there.
