Three weeks isn't much time to make a judgment I think. You'll possibly still have the itching so you're decision may be influenced by that unpleasant fact. I suggest you give it at least a month, preferably two. Unless you have a really dense beard, it will take that long to see what the real effect is. I'm just beginning to like mine to the point of keeping it and it's going to be three months, not weeks, on 5/12. But like the Ambassador says, post up a picture of the new chin mitten for review by the brothers.
PS, glad to hear all is going well w/ your daughter--things like that really show you've earned your grey!
