I have some and the imitation oils are horribly synthetic and smell nothing like the originals. They are good to buy if you have no idea what the scent they are modeled after smells like. I bought cool water, eternity and Issey miyake imitations. The Issey was the best since L'eau D'Issey is slightly bitter anyway. All the oils have a bitter synthetic smell so it worked in the Issey and smelled a lot more aquatic and lighter. Most of them get cloying too. My take is that they are just a fun purchase that should not be taken seriously.
