There are a lot of useless kitchen products out there.  I find it hard, for example, to imagine anyone making quesadillas often enough to justify a quesadilla maker.  The electric egg poacher also seems like it demands an improbably high, and frequent, desire for poached eggs, as well as a worrying inability to heat water in a saucepan.

But this is absolutely the least useful appliance I have ever seen:  the electric martini maker, which can provide them shaken, as well as stirred.  If you are not strong enough to either shake, or stir, your martinis, you probably already require a home health aide who should do it for you.  If you can lift the bottle to the rim of the cocktail shaker to pour in the gin, you can stir it around a little before you guzzle it.
