Pros:
Ergonomic handle
Easy to reach molars
Excellent, thorough cleaning
Ensures a 2 minute toothbrushing (which is pretty fucking long if you haven't timed it before)
Never had a cavity while using this brush (7 years)
Cons:
Batteries lose ability to keep a charge after a couple years
Replacement heads (every 6 weeks or so) are expensive
Disgusting when you unscrew the brush to replace the head
Overall Grade
A-
