We get a lot of product review emails in our inboxes, and this one struck me. From the email: "I'm sure you saw the news, but for summer revelers who take to the water while drinking alcohol, marine officers warn that this year brings a stricter law regarding what constitutes as drunken boating. It now matches drunken driving. Alcohoot is a smartphone breathalyzer that helps boaters know their number. The company has two goals: to reduce the number of drunken accidents and to make breathalyzers a commonplace device on the water." The device uses a "FDA-registered fuel cell sensor" that you plug into your headphone jack and, well, blow. It retails for $99.99. So tell us: is this something you'd want on your boat? Is this something you think is necessary? Would you keep it in your car? Who wants to review this for us?
