Hector is the man! This process is obviously not fun to go through and everyone who has to do this is automatically in "the red" emotionally. Hector makes this as relaxed and as easy as possible. He always answered my questions and returned my phone calls in a timely manner. He even stayed late for me on the day I was able to remove the device so I could be done with it ASAP. I personally referred three of my friends to him and would recommend to anyone who has to put a device on their vehicle to use him as well. Don't compound a big mistake and use some sketchy interlock company! Arizona Interlock's is the only way to go!
