I shave with a safety razor and straight. I do use a badger brush with AOS creams, proraso, and I have tried all of the classic T creams. I will say even though I have experience with a ton of good creams, this is surprisingly one of the closest, cleanest, irritation free creams I have ever used.
You don't need a brush with this cream which is kind of a waste for anyone who has already invested in good brushes, but even wet shavers who use brushes need creams that are good for "speed shaves," and this is definitely one of those creams. Since it is also a lotion type cream it is also transparent which is VERY nice for any shavers who maintain beards, chinstraps, etc.
Only major downside is this cream is more expensive than almost all of the top European creams and the overpriced AOS line.
