Title: Counterfeit or Oral B has gien up on quality
Review: Some of the brushheads are loose right out of the pack, the others becomes loose after very little use. When the burshheads are loose, they don't rotate back and forth the way they are supposed to when you hold the brushhead against your teeth; they can picnch your lip or cheek, and they can come apart in your mouth. And they can even come apart in your mouth. I've seen knockoffs that are of this poor quality. Either these are counterfeit Oral Bs or Oral B has let the quality degrade substantially.
