They are a bunch of crooks period.I had one dui a year ago when my time was up I was looking to get final calibration but had to get calibrated two days before they said go in for last calibration ( just making me pay for one more recalibration) then they were supposed to look at last 120days for any fails nothing happened after that I finally got back with them then they say homeland security sent them a note saying I had 2duis and need to pay for one more year I’ve only had one. Final got homeland to call me back and they said ther was no record of anyone sending them that note.so homeland security. Home land security is getting in touch with them I hope they can clear this . Heads up to anyone reading this so not use this company they are a bunch of rude crooks
