I just received my new RADIUS toothbrush in the mail and couldn't wait to try it out. I have to say, it felt a little awkward at first, being that the surface is twice as big as my normal toothbrush, but right off, I could really feel it messaging my gums like I didn't get with my regular brush. When I was through brushing, it made my mouth feel as clean as when I go for a cleaning from my dentist. I can't wait until the next time I brush!!! Great product!!! Glad I tried it!!
