NOT FOR ORAL-B PULSONIC TOOTHBRUSHES
If you need replacement brushes with the number S15-4 this toothbrush will not fit your sonic toothbruth.  These are not for the BRAUN Pulsonic Oral-B model.  Fortunately for the seller, these generic toothbrushes which are billed to fit sonic toothbrushes are cheap enough that it probably isn't worth it to send them back by the time you pay return shipping....
