We have all been there; it's the office pub lunch and you have all finished work earlier to celebrate the boss letting you all off the hook. Only problem is you have taken your car as you live too far away to walk home and a taxi will cost you an arm and a leg.

So you enjoy a pint before your lunch thinking it will sober you up enough for the drive home, only when you’re driving home you're always worried about police cars that seem to be coming out of nowhere and are following you like a magnet.

Well those days are over thanks to this Alcohol Breath Tester. No longer will you have to worry about thinking you're over the limit by enjoying that half pint of Carling shandy.

Plus it can be placed on your keyring as well so you will never forget to take it with you. We got our hands on this model off BudgetGadgets, so how does it work? Let’s find out.
