I bought this because I needed to make sure all traces of alcohol were out of my system before I drove. This has saved me many times from costly issues. Highly recommend!
Had the S80 and after 4 years it couldn't be calibrated. Guys did a great job in customer service and steared me to this one. So far it's great! Much better travel size and same pro grade calibration as the S80. Defiantly recommend.
I got this to replace my BACtrack S75 Pro. I like how slim the Trace is and it's easy to use. I know I can count on BACtrack for reliability -- it's sensitive to even the slightest amount of alcohol in the body.
This is my 2nd BACTrak. 1st one couldn't be re-calibrated after 5+ yrs. Not bad I think. From my research, these remain the most accurate and stable of the large variety out there. With two friends that have gone through the extended tortures of a DUI in the past 3 years, I'm comforted that I can confirm that I or my friends and guests are not put at risk, one way or the other. That is the true point of it. Be safe.
I have had a BacTrack Pro for years now. Before I returned it to be calibrated (a normal procedure you should do every year or so ($25), I decided to buy a new one in case I needed to use it while the other was gone. I ended up buying this model, and it is great. It's smaller in size that the old one, and give quick , accurate readings. When my old BacTrack arrived back from calibration (< 1 week total), I tried a test. I had a few beers, and then blew into both simultaneously. They both came with the same reading, down to the third decimal point!
We purchased these for a research project and so far they're working great, easy to use, long battery life. They also arrived quickly and we were able to get them to the site the next day! Thanks!
