    Cheap Breathalyzer Not Worth the Money at All

    Do not buy this breathalyzer. It is extremely inaccurate because they do not came calibrated properly. Sometimes when you haven’t even taken a drink it will show 0.001 which doesn’t make any sense. I hope the manufacturer recalls this product and fixes it to be accurate like the super expensive ones. And what ever you do, do not rely on this product and do NOT drive after drinking thinking your alright because this product is not accurate at all.

    The readings on the breathalyzer seemed to vary pretty substantially. But it made a great holiday gift.

    Can't be sure of the accuracy of this. Would be nice to compare with a police agency's version.

    I will be to where I can't stand and then wait the 20 min per the instructions and blow in it and it will tell me .08 or .09 so then I use the one that my cop friend has and I'll blow a .10-.23.

    After using on a few different occasions this thing is all over the place with its values. A lot of 0.00 readings when there is obvious alcohol in the system. Sometimes puts off a positive alcohol reading but still doesn’t seem accurate. It’s the cheaper of the companies models but it doesn’t work. **Also once you’ve opened the box, Best Buy will not let you return it.
