is selling a titanium solar powered toothbrush that works without toothpaste.
The Soladey-3 “cleans and sanitizes without any toothpaste, forever” promises the maker.
For $45, here’s how it works: solar power is used to send charges to the Titanium Oxide body of the brush, which in turn sends negative ions to your mouth. It is these negative ions which are apparently able to clean off the plaque. We’re gonna have to hassle them for a review model of this one, and will report back to you.
