    Breathometer - Blood Alcohol Detector - Black

    Not the best unit. Reads random depending on the person. I have a case on my iPhone and it takes an act of congress to get the thing to plug in and the app to detect it. Used it for about two weeks (eight times between me and friends) I plan to return it. If you don't have a case on your phone you might like it but poor design by the manufacturer on the headphone jack, should be a short cord not a slide jack if that is what they choose for an interface. Blutooth would have been a better option.

    Handy Little Device!

    By no means would I ever condone drinking and driving. But for those times when you have had a few drinks its handy to know how much you have had. This device is small enough to keep on your key chain. It works as advertised. Two things to remember. One, if you have a thick case on your phone it might not fit in the headphone jack very well. Two, it's very sensitive! While testing it with some friends at a bar I kept getting an error as it tried to calibrate. Then I realized that the bar was very busy and there was probably alcohol in the air. Sure enough, I went outside and it worked perfect. Back inside, errors again. back outside a second time, it would work fine.

    When it works, the breathometer seems pretty accurate, but if you don't do it exactly right, you'll have to blow multiple times, which can get tedious since you have to wait about a minute between each blow. If serious about this purchase, I would get the more expensive $100 version.

    The app takes too long to calibrate the sensor, although when I use it's really functional. But as soon a friend use it, it won't read anything. I think it's a great tool to measure if you can drive or not.

    While I am not sure how accurate this can be with the way it tracks the air blowing over the sensor, it is interesting to get a good idea on your BAC. This should not be used to see if you are just under the legal limit. If you aren't sure, just don't drive.

    I thought it was a pretty cool idea to have something readily available so when I'm out and about with the fellas I can check my alcohol level before I decide to leave the bar or the house to go hang out. It works pretty good I just think maybe the wireless one is better because you don't have to plug it into your phone if you have a case on your phone you have to remove the case.

    It works well if you blow properly and don't spit on it like my drunk friends did...otherwise your putting alcohol on it which guess what...skews the whole number...also it can become a bit of a game to see who has the highest BAC which is counter-productive...for something to leave in your car for yourself though its a worthwhile addition.

    Does what it says, results vary based on how hard you blow / how far away you are when you blow. Don't like how you have to wait 20 after last drink and 5 minutes inbetween uses (due to alcohol on the breathalyzer). I would recommend just paying the extra money for a better one.

    Set it up while being drunk. Proboally the first problem, but there are some kinks that need worked out. Can't have your sound off or it will not work. Overall once you figure it out. It is still hard to work, but I do like the functionality of it.

    My husband bought this because it was on sale for $10, we thought it was funny. Only tried it once and it was definitely off, I believe it was giving to low of a number considering how much I drank. Haven't tried it again yet.

    I tried this and have not been very successful at getting it to read and then it says to do again and you have to wait 40 seconds while it reboots to try again, which is ridiculous.

    its ok but I don't trust the numbers. Really would need to benchmark against cop unit. If I did read at or just below 0.07 I would not risk driving at all.
