What people are saying.
Big Brush with Replaceable Head
I mainly bought the brush for the green reasons but after my first time using it having a bigger surface makes it easier to get every spot!
I’ve been using Radius toothbrushes for 1 1/2 years. Absolutely the best toothbrushes ever. I prefer the small head, but my husband likes the big head. When my first toothbrush arrived, I thought it might be too soft, I used it anyway, and fell in love. I also love that I can just change out the brush and not contribute to excess trash.
I have been using Radius for years. The Big Brush has a nicer feel to it than the regular Radius brush.
I have been using Radius toothbrushes for a while. I wanted to try the replaceable head toothbrush, but was concerned that it might be wobbly. It wasn't wobbly at all! The same great toothbrush made better for the planet.
