Review on Philips Sonicare for Kids 7+ Genuine Replacement Toothbrush Heads - 2 Brush Heads, Turquoise and White, Standard - HX6032/94 by Rhonda Quire

Toothbrush Heads with any design on the back of the brush head causing a crack in the material, allowing moisture to penetrate the interior of the brush head and leading to moisture build-up and mold growth at the base of the bristles. I tried different brands and came to the conclusion that this is bad design. My heads, which are non-porous at the back, have no problems. Brush heads are non-refundable, so buyer should be careful. If you are looking for baby attachments, buy a soft/sensitive adult attachment. They also have smaller heads.
