I have the Proraso green pre-shave, and I like it (not sure if it is very effective, but it is very pleasant). It has a super strong IMO menthol scent which is great, but can clash with or overpower whatever your lather may be scented with.
I recently got the Proraso red pre-shave, and I like it even more -- lovely mild sandalwood fragrance. I'm still undecided about the true benefits of the product, though. I can tell you that using these pre-shaves is a terrific example of the axiom less is more. Using too much of this stuff will gunk up your razor and spoil your lather.
I find that just a very small amount (pea size?) rubbed into my wet beard is best. I have yet to try their white pre-shave, but the Proraso white Liquid Aftershave Cream is a favorite of mine.
