Which one should you pick?

Intoxalock

The lower starting lease: $5 a month less, $60 over a year. The only one of the two in North Dakota and South Dakota.

Smart Start

The higher Trustpilot score (4.6 against 4.4) and a published install price, as low as $150. The only one of the two in the District of Columbia, Virginia and West Virginia.

These are starting prices. The price posted for your state and the number of calibration visits your program needs decide the real total, so compare the quotes you get there.

Where a company posts no install price, the 12-month row uses MADD's typical $70 to $150. Calibration visits come on top. Work out a total for your months.
