Q: How many brush strokes a minute does it have? 62000 or 31000?
A: 1 brush STROKE (an up and down motion) = 2 brush MOVEMENTS (one up, one down) And that means … 31,000 brush-STROKES-per-minute = 62,000 brush-MOVEMENTS-per-minute. They describe the same rate of speed (frequency). So, there’s nothing new and improved here. Both brushing action descriptions are equivalents.

Q: What size replacement brushes work with this model? Will C1 work?
A: Actually, the former answer "it uses a C3 head" is belied by the company provided photo showing a C2 head. What the little "radar" symbol means, sort of like my computers WiFi presence symbol, is not stated. Looking further, that seems to be the Brush Sync chip symbol, to activate the LED light that it's time to change the brush head. Your handle may not have that capacity, but all brush heads C1, C2, and C3 will work in the handle

A: It only comes with one, but replacements are not expensive and you need them every six months or as needed.
