ZBK Breathalyzer Rechargeable,Professional-Grade Accuracy Alcohol Tester,Alcohol breathalyzer,Portable breathalyzer,Suitable for Family, Personal, Driver, Professional use

Love this! It is very easy to use, I’m confused as to why anyone would rate it otherwise … turn it on, wait until it counts down to zero, and blow. Seems accurate, I have twice compared results with results on friends’ units that were different brands and they matched up both times. It is a lot easier to reach the legal blood alcohol limit for driving than most people think, making this an indispensable item for anyone who thinks they are “fine to drive” after a few drinks. And it costs a hell of a lot less than a DUI, not to mention could save lives. Well worth it for that alone.

This little gadget is a relief to own. Works as expected, and great to have when you’re unsure of your BAC. I’d recommend this to any of my friends! The size is nice and the fact that it’s a usb charge is super convenient. Would buy again!

This is an easy way to test the alcohol in your system, or in someone else's system. It's quick and easy to use..

It’s good

This product does not accurately read BAC. Simple as that. I work in a field where we use these devices. Has nothing to do with user error.

Worth the money ... this is a must to monitor your BA levels. Do not push your BA levels to .049 ... the device is accurate but not guaranteed to be the same as a gov't tester. I recommend backing off your drive home until you get a reading of .03 or less ...

It reads high when no one even blows into it

I find it important to know where my blood level is at. I believe it to be accurate. Do I stay home, or do I go to the store, now I know.
