Atomic auto did a great job installing. However, I was told the install was $195 by Lifesaver, but the shop charged $225. Also was told it would be 1 hour and took 2.
Atomic did great, Lifesaver needs to get their numbers correct.

It was not tax that changed the install total, their total was $225 PLUS tax, not $195 as I was told. Also, unless your calls are transcribed, why would anyone have 'noted' that they told me the install was 1 hour?

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.
