They are saying it will help your girlfriend pin you down when you lie about how many bottles of beer you quaffed off last night. But it could as well be the decider in the competition with your ale-guzzling buddy. The Beer Tracker, a plastic bottle opener with an LCD screen, displays how many bottles have been opened to put all debates to rest. This latest among kitchen gizmos, which is retailing for £4.95, has a battery built into the handle. The counter can be reset at a touch of a button.
