What people are saying.
I've used Radius toothbrushes for almost 30 years and was quite disappointed when they announced the "original " was no longer being made. After awhile, i decided to give the new model with replaceable heads a try. I like this new model more than the original - it just feels great! I'm heading for 40 years as a customer now.
Love the handle but I would love a medium or firm brush this size!
The docs are the amazing and so cute! We’ve already known and loved the brushes for years, the replaceable big heads are our newest addition and we love them! Keep doing what you’re doing!!!
