So are you over the limit? Of course if you have to ask yourself the question, then the answers very probably yes, and you should be walking home. This nifty little gizmo is an ever-ready portable breath tester that will tell you if your alcohol content is over 0.25mg/l. Simply blow in the end, and if you're over the limit*, a red LED goes on, and it's the bus for you.

As well as telling you whether you're a tad on the merry side, the unit also incorporates a UV tester. Once exposed to sunlight, the white fan sensor on the pen changes colour according to the level of intensity of the sun's UV rays. There's nothing worse than being pissed and burnt, so kill two birds with one stone, and make sure you're protected from both!
