In your opinion, what is the invention that people STILL buy today that you feel is a failure?

For me it would have to be those ice cream dots.

1) They claim to be future food, but it was made in the 90s.
2) It tastes more like ice with sugar sprinkled on it than ice cream
3) Its more expensive than ice cream.
