I have 2 WSP Prince silvertips, the 2 band and 3 band purchased on BST for a combined $60. They both whip up great lather on soaps and creams with minimal effort, and both have very soft tips. I see people spending $100 and well beyond on brushes, is there really a significant difference? Outside of Elizabeth Hurley lathering my face, I can't imagine it getting better than my Prince's, what am I missing?
