The Wall Street Journal ran an article this week about a handy little gadget you might want to get in line for. A straight line. And hold your hands down to your side.

Breathometer Inc. makes a smartphone breathalyzer test that can instantly tell users if their blood alcohol level is too high to get behind the wheel.

Last month the product was introduced on the TV show Shark Tank, and it was the first product to receive unanimous backing from all the sharks, including Dallas Mavericks' owner and savior of the Greenville St. Patrick's Day parade, Mark Cuban.

The Breathometer, weighing in at less than one ounce, attaches to the top of a smartphone. Presumably after blowing in it, the device will provide the user with an accurate reading of their blood-alcohol level, including how long it will take for a high level to metabolize, or "get back to zero." Per the company website, the gadget is a "FDA-registered device which boasts accuracy that compares favorably to other high-end breathlyzers."

Since rolling out on Shark Tank, the product has received high-roller backing from venture firms Dillon Hill Capital and Structure Capital -- a company that previously invested in Uber, the taxi start-up that has gone a few rounds with the City of Dallas. Structure Capital paired the two companies and now, if you're too toasted to drive, the app will give you the option to hail an Uber ride with the push of a button.

The company is currently taking pre-orders online for $49 a pop. The website reads that orders will ship this fall, however, on the actual order page, it says that the product will be shipped as soon as inventory becomes available.

Keep the Dallas Observer Free... Since we started the Dallas Observer, it has been defined as the free, independent voice of Dallas, and we would like to keep it that way.

Producing stories on everything from political scandals to the hottest new bands, with gutsy reporting, stylish writing, and staffers who've won everything from the Society of Professional Journalists' Sigma Delta Chi feature-writing award to the Casey Medal for Meritorious Journalism. But with local journalism's existence under siege and advertising revenue setbacks having a larger impact, it is important now more than ever for us to rally support behind funding our local journalism.
