I am leasing an intoxalock from Consumer Safety Technology, Inc. CST I've had it in my car for 1 month now. Last week I was leaving for work one day, did the proper starting procedure after taking a drink of water, the machine read BAC 000, the car started. A short time later "5 minutes" a rolling retest was required, I took a drink of water before blowing in the device, "because CST recommends it" the device read BAC 027. The device immediately asked for another sample, this time reading BAC 000. Upon arriving a work, and turning the car off the device informed me it was locked out, and that it needed servicing in 4 days. When i got home from work I called CST to inform them of this. The first words out of the ladies mouth was how much it was going to cost me. $ 75.00 for the next device, and $ 15.00 for shipping! I tried to explain that the device gave a false reading. That I had no alcohol that day, nor did I eat before driving, use mouth wash, brush my teeth, etc. She didn't want to hear it! According to her the machine just does not make mistakes. My debit card was charged $ 90. . My replacement device arrived the next day, and I swapped them out the day after, which was Friday. After installation I tested the device to see if it worked, it read BAC 000, so I turned the car off, and it sat till Monday, when I had to leave for work. I did the proper starting procedures again, the devise read BAC 000, the car started. Again, a short time later a Rolling Retest was required. I followed the suggested procedure, and blew. This time the device read BAC 047, immediately it asked for another sample, this one read lower but not enough to turn the horn off. It took 4 samples, one right after the other to finally get the reading to BAC 020, "a time span of about 3 minutes" to get the horn to turn off. When I got to work I turned the car off, and did the starting procedures, the device read BAC 000. After work I called CST to inform them of this lockout, and again the first words out of the ladies mouth was the money! Another $ 90.!!! And again, did not want to hear about a false reading or help Me figure out what is causing it! This lady was very rude, and set on the fact that the machine is pretty much flawless! CST had Me sign a contract for 6 months, that was just my first month! If You cancel their lease it will cost $ 200. They got my debit card #'s So they will withdraw any funds that they deem fit!!! At this rate any moneys I may save on fines by having a intoxalock "up to $650. Will go to these thieves!!! DONT DO BUISINESS WITH THESE SHISTERES !!!!
