Installed the 0.0 calibrated interlock with no further information about the lawful 0
Installed the wrong 0.0 calibrated interlock device at time of initial installation instead of the court ordered 0.2 bac calibrated interlock. They did later refund a violation caused my this mishap. So that I respect for making it "right". Always ask for the 0.2 BAC calibration ASAP. Because they will not tell you about the fact there is 2 different calibration installs. You have to find out for yourself. I found out by having to ask off work to go pay for a high alcohol violation where NO alcohol was consumed whatsoever(falsely triggered). So I started asking questions... Unfortunately I had to find out the hard way (I feel I was purposely uninformed). So I pray you read this review and ask for the lawful and CORRECTLY calibrated 0.2 bac interlock device install [look on back of driver's license for "0.2 bac"]
