"A low-cost sonic toothbrush whose main feature is a two-year supply of brush heads."
The 40,000 strokes-per-minute rating means this sonic toothbrush vibrates at a standard frequency for the category, using fluid dynamics to help clean beyond where bristles physically touch.
This is for someone prioritizing low initial and running costs over brand reputation. The included two-year supply of brush heads makes it a compelling package for a first-time electric toothbrush user or for a secondary travel device.
Users who value proven long-term reliability and a guaranteed supply of replacement heads should stick with established brands. The availability and cost of replacement heads after the first two years for this model is a significant unknown.
