How is quip Ultra different from a standard quip Sonic Toothbrush?Updated an hour ago

Both quip Ultra (and the original quip Sonic Toothbrush) use high-frequency sonic vibrations to help remove plaque. However, quip Ultra delivers greater power and 16 intensities, while the original has a single, more sensitive mode. Unlike manual brushing, or the original quip, Ultra’s bristles do the work for you — no scrubbing required.
