I have tried some of their bar soaps and they are fantastic. It is questionable really how much they really help extend the scent; but probably more than a little bit. They're hard milled and last a good while too. (Issey Miyake sells or sold a bar soap that made me about as mad as I get at this sort of stuff. It was glycerin or some such and while it smelled great, it lasted about 4 showers.)
I have also tried their GIT AS balm and it is outrageously opulent and clearly a high quality product. You know the second it hits your face: "This should be pricey shyt."
Haven't tried any of their shower gels. $78 just rankles me and I'm not generally one to be thrifty when it comes to my grooming.
I know some in here are big fans of the GIT shave soap. Never tried it.
Have read mixed reviews on the deos. I've been burned on a couple of non Creed deos matched to scent which proved highly ineffective on me.
They Creed bath & body line is $ pricey $, but I will say that they are very clearly high quality, top notch products. They are not skimping here. If you're of a mind to splurge on that kind of thing, these do deliver. (Pessimistic about the deos though).
If you try one of the shower gels, let us know what you think.
