Let’s just get one thing straight here, we don’t condone drinking and driving whatsoever, but can stand behind a device that alerts people when it’s not a-okay to mosey on home in their cars. And that's where BACtrack Mobile comes in. The tiny, $150 breathalyzer syncs with your iPhone’s Bluetooth to let you know if you’re sober enough to drive. This police-grade device is the real-deal, of course, with techie upgrades that make it easy to tote around, share, and ultimately prevent drunk driving. We'll all for scooping this up and throwing it in our pockets before a night out — safety first, people!
