I absolutely love these toothbrushes. I purchased radius toothbrushes for my grandchildren and they love them. No more fighting with them to brush their teeth. Love having extra toothbrushes on hand, I have given them to my friends and family and they also given them raved reviews. My teeth have never felt so clean. My husband has had problems with receding gums and he also loves his new toothbrush. I would encourage anyone who has never tried radius toothbrushes to give them a try, you will never go back to the old standard ones.
