Negative Positive
Title: Good
Review: Fits and cleans my teeth much better than Braun Oral-B Extrasoft,Flexisoft and Interspace Brushheads. Didn't cause bleeding. Contra: incompatibility with SmartDisplay function of Triumph 9400. Interactive feedback display didn't indicate when it was time to replace this brushhead even when it looked like it was overworn (blue bristles turned curly and almost completely white).
