Breathe Testing Pen: A life Saver

Needless to say drinking and driving is dangerous and we all are obviously aware of this. In spite of that when we drink we aren't aware of anything and we often cross the limits and get totally sloshed. So, it's advisable not to drink and drive, but for every plan you should always have a backup. This small pen 'Breathe Testing Pen' with a built-in mini breathalyzer can indicate if you have reached your limits. What you basically have to do is blow into a hole on top of the pen. The whole process takes just a few seconds. If you are out then the green LED turns red, indicating it's a better idea to go back in a taxi. It's very small and can be carried everywhere with convenience. The market price of this life saving instrument is $35.
