Meanwhile, I have to say that my major brush heads like better than the little ones. But that is subjective and must be decided by each itself.
With the cleaning performance and the results I am very satisfied. As I wrote in my review of the Sonicare sonic toothbrush, I've never had before so clean teeth by brushing.
The tooth surfaces and the interdental spaces feel really very clean. I use additionally to really get flossing everything perfectly clean before brushing.
I highly recommend this brush heads!
