Query: Oral B Dual Clean Brush

At first I was hesitant to try this brush, but I thought because my teeth are a bit larger It may be worth a try. I am pleased with the Dual Brush. I feel like I am getting more cleaning done. This brush does seem to run the battery down a bit faster, but this is no problem because I have 3 Oral B handles I rotate. I should tell you that I do not keep my brush in the charger all the time. I run my brushes down and then charge. I think this maintains a longer life.
