Ever been in limbo about whether or not you are safe to drive after a couple drinks with friends? Most of us have had that dilemma, and nobody wants to make the wrong choice. The Aura Breathalyzer ($150) aims to improve your judgement in those situations, and is doing it with a product that not only works well but looks great too. Utilizing fuel cell sensors, the same technology used in Police handheld devices and most courts issued vehicle ignition interlock systems, this breathalyzer gives you the piece of mind needed to decide whether to get behind the wheel or ask for a ride home. And the sleek, scratch resistant display only adds to the attractiveness of an already incredibly practical product.
