I don’t recommend getting it. I have it for 3 weeks and it’s giving problems. It’s says blow harder before i even blow in it. This happened 3 times in 3 weeks. But twice in one day. I was on my lunch break stuck then driving home after work it happened again. I had to pull over and was stuck again. Then after going through this episode the vehicle won’t start and the horn beeps for about 2-3 minutes embarrassing loud. I recommend smart start. I gave it 1 star rating and google put 5. I don’t know if it’s the installation or the product. Terrible experience!!!!!!

How do I use my ignition interlock device?
During your appointment at LifeSafer, you'll receive comprehensive guidance on operating the LifeSafer ignition interlock device. This includes instructions on proper usage, what to avoid prior to using the device, and tips for ensuring it operates effectively. Please do not hesitate to ask your certified installer any questions you may have about your car breathalyzer and our services.
How much does an ignition interlock device cost?
The cost for installing a LifeSafer ignition interlock device, also known as a car breathalyzer, usually ranges from $70 to $150. This is a one-time installation fee that you'll pay at the beginning of your lease period for the device. You'll pay this fee directly to the service center that installs the device in your vehicle. Additional fees are usually incurred every time you must have your device calibrated and vary by state.
How does an interlock device/car breathalyzer work?
After the device is set up, drivers need to breathe into the car breathalyzer's mouthpiece to provide a sample. This device checks the driver’s breath alcohol concentration (BAC) to measure it is within legal limits. Typically, if the BAC is below .025, the driver is then clear to insert their keys and start the vehicle.
