Fraud based company. The device has malfunctioned 3 times resulting in B.A.C readings over .020. After the 3 minute countdown to reblow, I blow .0.00. Impossible for the human body to from a reading of over .020 to .0.00 on 3 minutes time. The company requires a recalibration at $20.00 as well as an added fee of $75.00. This is a full on money grab from intoxalock. I then get told there is zero options to file a complaint or a grievence. I also get told that they cannot reverse or negate the $75.00 charge. This is a lie. It was reversed in 2020 when this 1st happened.
