The talking beer mug recognises when your beer is at a critically low level and pipes in with the following advice…
"Your beer is running dangerously low" A bit like the Knight Rider of the drinking world the artificially intelligent Never Empty Mug takes it’s responsibility very seriously indeed.

If you ignore the first warning, you’ll hear the following….."Refill immediately – danger of sobering up"....but once the mug has been replenished, the mouthy mug reverts to polite mode……."Cheers!"

Of course, the never empty mug has a couple of drawbacks. It’s complicated voice technology means it has to be the size of an industrial kettle, and presumably if you keep refilling the beer mug at some stage it will get drunk….
