Most useless gadget ever?

Q&A

I just wanted to know the most useless gadget that you have ever owned. To get the list going, my number one is the black and decker Autotape.

Take a simple device (measuring tape) that works perfectly, over engineer it (tripled in weight and size) and produce a product that does not work is infuriating and a total waste of time.

Any other suggestions welcome.
