Have you just been convicted of a DUI and have to face the penalties? I just finished my DUI process and this was everything I needed to get through it without extra struggles. The kit includes a commercial grade police breathalyzer that I paid almost $800 for. It comes with extra tubes. This is what you’ll need to know when to stop drinking the night before and still be able to start your vehicle and get to work if you have an ignition interlock device as required if you blow over a .15. The kit also includes an ignition interlock disguising device that makes sure your ignition interlock device looks like a water bottle instead of what it actually is, which helps when you’re leaving work and don’t want to look bad. It also comes with a heater that I put in my truck and plugged in because I did not have remote start. The ignition interlock device does not work unless it’s above a certain temperature and that will delay you getting to work. Sorry you’re going through this if you’re looking at this ad it was not easy but these things sure made it easier for me to get through it. Let me know if you’re interested. $425 OBO
