A compact, battery-operated breathalyzer helps quickly show your blood alcohol concentration.

It's summertime, July 4 is right around the corner, and America's soccer team has been doing great at the World Cup. And those are just a few excuses to drink and celebrate.

The question is, how do you know when you or your friends have drunk too much to drive? I have one answer, in a simple and compact form. It's the AlcoHawk Slim Ultra.

This is a little battery-operated breathalyzer that immediately shows the alcohol level in your bloodstream. The device has just one button and a little round LCD screen. Press the button and blow into the mouthpiece, and after a few seconds, the LCD will show your blood alcohol concentration (BAC) on a scale from 0 percent to 0.40 percent.

The device seemed to work as intended in my trials. Once I blew into the collapsible mouthpiece, the LCD started a countdown from 99 at a one-second-per count pace. After about 20 seconds, the countdown ran faster, and after about another 10 seconds, it showed the BAC indication.

Q3 Innovations, maker of the AlcoHawk Slim Ultra, claims the device has an accuracy margin of .01 percent to .02 percent and recommends you have the device recalibrated for better accuracy once in a while if you use it daily.

The AlcoHawk Slim Ultra is available now and costs around $50. It will cost another $20 each time you have it recalibrated.

Considering the total cost of each DUI is thousands of dollars, not to mention the fact that you can't put a price on safety, it's totally worth it to have one around. Apart from the AlcoHawk Slim Ultra, Q3 also has a disposable breathalyzer, called AlcoHawk One Test,  that costs $10.
