Burst Pro Sonic Toothbrush
The Burst Pro is a credible Sonicare alternative built around two ideas: charcoal-infused bristles and a $6 brush-head subscription that ships every three months. The handle vibrates at 33,000 strokes per minute, runs for nearly four weeks per charge, and survives the kind of bathroom drops that have killed two of my Sonicares. After four months of daily use the cleaning performance lands within touching distance of a ProtectiveClean 6100, and the head economics are genuinely better than buying $12 Sonicare heads at the drugstore.
