Negative Positive
Title: absolutely brilliant!
Review: those radius corp. folks are some forward thinkers allright! the radius is a completely different toothbrush. very ergonomic - right/left handed - larger brush head, cleans like no other, gentle on the gums AND the handle is recyclable cellulose! the radius toothbrush cleans better, fits better, handles better, feels better - it is far and away the best i've ever used. (i've been using them for several years now.) once you try a radius (or radius scuba), you'll never be satisfied with your old toothbrush!
