Battery-free toothbrush is powered with a twist

As you would possibly surmise, there is a catch: the brushes aren’t low-cost. Early backers can get a starter package for $49 (a brush, three head refills and a journey case), however there have been only some dozen left as of this writing — and there weren’t many extra for the $89 cleansing package or $96 two-pack, both. And you will have to attend till December 2018 even when you do get a pledge in. If Goodwell pulls this off, although, it will be no small feat — you will have a powered brush you may tackle trip figuring out that it will not conk out in mid-scrub.
