Brookstone Grey ZAPI UV Toothbrush Sanitizer It bobs, it wobbles... but most of all, fun, colorful Zapi zaps up to 99% of germs and bacteria* on your toothbrush in just 7 minutes using proven, germicidal UV light. To sanitize, simply insert your toothbrush and press the button. When the light stops blinking, your toothbrush is germ-free! It can even be safely stored inside Zapi until the next time you brush. Use with your favorite manual toothbrush or most small electric heads.
