VIOlight is a portable toothbrush sanitizer, for travel and home use:
VIOLight sanitizes your toothbrush and prevents contamination build-up. Even after a thorough rinsing, thousands of germs can remain on your toothbrush, creating the potential for harmful bacteria to grow. In just minutes, VIOLight sanitizes your toothbrush with UV light. After each use, place your toothbrush in the battery-operated case; the UV bulb automatically shuts off after the sanitation cycle is done. Case has a removable tray that stores the brush until your next use. Bulb lasts 1,000 hours.
