      Tremendous Purchase


      I have had my Bactrack for nearly a year but held off on reviewing so I could give it a good test. Over 110 tests later and this unit has been top notch all along. Consistent and quick results, I have tested friends and family with it and on more than one occasion myself or someone has decided not to drive as we were to close to or over the legal limit of 0.08%. I've also learned a lot about how alcohol effects me differently depending on what I have had to eat, how active I have been that day, how quickly I have been drinking and what I have been drinking etc. Came with a nice case and extra mouthpieces that I wash in the dishwasher. This unit is in my car whenever I go out. I highly recommend it.

      Accurate and Easy

      I bought this item to obviously be able to check people's alcohol levels, and I have to say it is easy to use and tests accurate. However, the restrictions of having to wait 20 minutes after eating drinking or smoking is a pain. The mouth pieces it comes with are great and easy to identify which way to place them into the machine, but the replacement ones do not have a ball in them so you have to pay more attention to what you are doing. I have used this 20-30 times so far without any problem and have shown other people how to use it also without any difficulty. I wouldn't rely on it vs. one a cop would carry, but it does seem accurate and it super easy to use and seems really durable. I love the little case it comes in that I can throw every thing I need in one spot. If you need one or just want one, check this out.

      worst breathalyezr ever


      i feel like i was cheated out of my $200. there's a lot of things i could buy with $200 and a breathalyzer that doesn't tell me my bac isn't something i'd want. i got this bactrack breathalyzer thinking i was buying the best model available. i'm aware that i'm not buying a police breathalyzer, but i'm also not buying toy. the only thing that disappoints me more, is that other reviewers had a good experience and i didn't. i'm confident i used the device correctly, but when i would have 3 drinks, it would read .01. and when i'd have 5 drinks it would read .03. i sure didn't feel like a .03. good luck with this, but i'd look into another brand than bactrack if this is their best breathalyzer.

      Top of the Line


      I am pleased with the performance of this product. It's simple, it works well, and the price tag is nothing compared to if the cops get you. I reuse mouthpieces and haven't had any problems - definitely no need to throw out a mouthpiece after a test. The screen is bright and easy to read. That's a plus. Results are consistent test to test. If I blow 2-3 times in a row I get similar results. This was not the case with a previous breathalyzer I had purchased. Definitely worth the money to get this type of higher end unit.

      disappointed with it


      i was expecting something better for the amount i spent. the material felt cheap and light in the hand. regardless it read the result pretty quickly but my son blew into it to see how high he could get it and now the device doesn't read accurately. i called tech support and they want me to send it to them to have it serviced which was almost half the cost of the machine. apparently the warranty doesn't cover anything. i returned it to best buy and cut my losses. i'll do more research before buying another breathalyzer online.

      More accurate and consistent than expected


      This model is the real deal. I have a friend who's a cop and we compared this model with the police one, which was much bigger, and the results were almost identical. I tested first after just one beer: 0.011 %BAC and 0.010 on the police model. Then after 3 more drinks over two hours, 0.045 on the S80, and 0.043 on the police model. I'm impressed this is available for only 200 bucks. Good technology.

      Just didn't work, ever.

      • Verified PurchaserVerified Purchase

      I was so hoping that this would work. I had read a number of reviews on the various home-BAC devices and this one seemed to have the fewest negative reviews. Unfortunately, it simply never worked - ever. I did a little home test of the device. Blew prior to having anything to drink. .00. Drank a two-shot drink, waited 20 minutes, blew. .00. Not a chance I was .00. Also, some of the function buttons didn't work. Returned it. Maybe I just had a defective one, but I won't be taking the chance and getting another.

      super accurate and easy to use!


      I have purchased other(read: less expensive) breathalyzers before, but I am really impressed with this model. It's seems to be very accurate, and doesn't read a false positive if I breathalyze someone who hasn't been drinking at all after someone who has. I like to have people use this at any of my parties because I will not let someone drive if they are over a .05 (I know the legal limit is .08, but better safe than sorry). I love it!!!!
