This is just my personal experience. I’ve used the old small pen version banisher before, I think it works even better than the banisher 2.0. The surface of 2.0 is just too big it can’t get into those small areas. And I think because of its surface size, the pressure is not distributed evenly from the center of the circle to the outer edge of the circle. My mom used the roller version, works better than my 2.0 too. I saw u don’t produce those two anymore only 2.0.
