I see what you mean, Link. But the benefits are worth it. After the initial application, you only have to do a wipe down with it and you're done with cleaning. The powder residue and gunk seems to be repelled by the Eezox witch means no more scrubbing. The protective barrier is there, just don't see it.
I've had good luck with it. Sorry to hear of your disappointment. No matter how great a product is, it may not be for everybody. "There's more than one way to skin a cat"...
