I had to get use to using it as I am new to electric toothbrush use. I am sold. I love the timer for each quadrant which means I get a solid 2 minutes (or more if I want) of brushing. No reason to "rush" through a brushing. After 2 months my dentist and hygienist have noticed improvement in teeth and gums.
Pros
Easy to use and makes me more thorough when brushing. Improvement for me were quick two months approx.
Cons
So far nothing negative. Have to remember to keep it charged but not an issue.
