There are many great ways to end a night out, but driving home under the influence isn't one of them. Fortunately, if you have a good breathalyzer, you can properly prepare for such situations. With that in mind, BACtrack's app-connected Mobile Breathalyzer is 33% off for Lifehacker readers.

The first thing to say about the BACtrack is that it's tiny. Take-it-anywhere tiny, in fact, at 1.75 x 2.75 x 0.63 inches and 1.7 ounces. Crammed into that space is a Xtend™ Fuel Cell Sensor, as used by law enforcement, and Bluetooth 4.0 so it talks to any modern iOS or Android device. Once you've paired the BACtrack with your phone and downloaded the app, it's simple to use: just switch it on, blow, and a your results show up on in the app.

The BACtrack is currently 33% off, making it $99, so now is a good time to pick up a DUI-avoiding wingman…scroll down for more.

"…BACtrack also provides detailed stats analysis so you have a more accurate idea of how well you hold your liquor, lets you easily contact your designated driver when drunk, and most importantly, makes it easy to know when getting behind the wheel of a car is a dangerous idea…Overall, we liked this thing a lot." – Gizmodo
