Review (4/5): Effective, but use sparingly
This oil is effective for taming the random parts of the beard that are going in some odd direction on any given day. It also seems to be making the beard less dry and bristly. You probably wouldn't need it on a trim beard, but those of us with manly beard start needing a little something at some point.
Like any oil, it can be annoying if you absent-mindedly stroke your beard and then touch your face with your hands. It does not irritate the eyes, so that is good, but you have to remember to go easy on the oil and pretty much keep your hands off your beard.
Modern Barbarian's beard balm is a better product for daily use in that it doesn't make your face and hands oily. The balm really does the job with no downside. This oil does a better job re: getting the beard ready to be combed into a presentable shape, but comes with the down side of being oily. I use the oil if I need to look presentable for something important, but I rub a little of the balm in every day.
