Everyone thinks they’re unique. More than 50% of us think we’re above average in intelligence, looks, and wit. Then there are businesses and their products:

“There are 345,000,000 Google matches for ‘ultimate’. ‘Best’ is way behind at 300,000,000, while finest only can score 119,000,000. Unique gets 664 million.” (Seth Godin)

It’s usually a turn-off to call your product by these names, or add meaningless taglines like “Great”. Perhaps there’s one exception: Fantastik.
You spray, it cleans, and your reaction is “wow, this stuff is fantastic”. And there we have a classic example of priming.

You don’t care if a product is the 409th formula (Is that 369 more tries than WD40?), Clorox sprays strike fear in all those who loath the bleach smell, and find me someone who really walks into the cleaning supply aisle wanting every surface in her home to smell like lemons. It’s best not to make such specific claims and promises - people want this product to do one thing. This stuff just cleans the dirt, and that’s fantastik.
