Avoid at all costs. Charles is the owner, and sole…read moreproprietor of this shady establishment. I am sure that he will go "above and beyond" for you, as stated numerous times in my phone calls with him. After a week of assuring me that he had the interlock device, and day after day of excuses as to why he doesn't actually have any in stock, we finally made an appointment where he said "he/they" would be there. 10am arrives and we show up to get the device installed. CHARLES is no longer operating out of this location. So then we go to the other location as advised by the people in the shop next to his. Now at the new location, and the new people say he moved from there too. After several missed calls/texts/ and voicemails, Charles answers the phone hungover and drunk at 10:20am telling me that he just needs to shower and then he will be there. ARE YOU SERIOUS. ARE YOU MENTAL??? Who operates a business like this!? This should be all you need to know about how fun it is to deal with Charles and this "company". IF YOU SEE THE NUMBER 916-275-2292, or the name CHARLES, attached to any interlock service, just know that he's a total waste of time, and if the companies name is different than "California Ignition Interlock" it's because he constantly has to change locations and business names to avoid his awful reputation. Thanks for the huge waste of time!

Don't judge me! It's all over with now thanks to the staff at Cii and Charles the owner. They made…read moreme feel less like a degenerate and more like a human. Overall price wise and service can not be matched, albeit I hope those of you out there never need it. In my humble opinion Charles and his team made the experience as best as it could be. Not that this guy will be visiting this place again, ever. Best of luck!
