No, thanks. I'll stick to the tried and true method. They don't call it a "splash" for nothing, y'know.
I suspect that using one of those roll-on vials will not dispense enough product to cover your entire beard area, unless you go over and over and over. As an alternative, you could rub one of the vials on your hand, and then apply it to your beard ... but then, you're back to the original situation of having to re-wash your hands and wasting product.
