This is the same technology as the police use and they have to calibrate theirs, LOL, suckers.......I dont normally write reviews unless I am mad about the product (I know its wrong), but I am a truck driver and I dont have much extra time. So this is an exception, I have to let everyone to know about this product since its PRICELESS!
This has saved my *** and life a few times. Dont buy a $100 or please not a $20- $50, or any cheap ****** phone app these are not real breathalyzers. They are for college kids to see how ***** they can get. THESE CHEAP PHONE APPS ARE JUST WAITING TO PUT YOU IN JAIL. I know I bought a $100 bactrack phone app mobile Pro and I bought the best $130 s80 pro bactrack (top of their line) so I thought I was golden, no worries, boy was I wrong, what a waste of time and money. Never again!
The ones you see on ebay and amazon for under $130 can not be reclaibrated (read the reviews on the best selling bactrack, they can not calibrate them, the reviews are all over the internet, maybe not their site I dont know) they last about 3-9 months and then they die and they want you to purchase a new one, stay away, they are not worth a $10,000 DUI!!! And all that comes along with one, losing your job, your car insurance is yanked from you, sometimes lose your JOB then put an interlock in your car and pay $50 a month lease for it, you dont even own it, IT REALLY SUCKS!!!!
Dont chance it by trying to save a few dollars its not worth it , trust me. Its not only the $10,000 or more but jail time, all the driving classes, alcohol counseling and alcohol anonymous, etc....etc..... They treat you like a alcoholic.
Please buy this REVO or the AL-9000, I have had that AL-9000 for 7 years and I have NEVER had a problem with it. I should have never tried the other brand but they are all over the internet to reel you in, my mistake. I LOVE THESE AND WILL NEVER CHANGE.
