What a great product concept and what a smart name. It's one of those simple ideas that I wish I had early in my career when I worked in the oral care category.
Another cool idea in the toothbrush world is the Volight® Toothbrush Sanitzer - a system that eliminates bacteria that thrive in the warm, moist environment of bathrooms. The sanitizer, beautifully dsigned by Philippe Stark, uses technology common in hospitals: a germicidal UV bulb to kill germs. A blue glow lets you know the sanitizer is working.
Interesting to see how both innovations use light in a smart way.
