Great money saver
They fit my Oral B toothbrush with no problem, totally compatible. Oral B heads have permanent colored marking. These have removable bands to color code as you wish. So one package can be color coded as one round of brushes for a family of four, or four subsequent heads for a single person, or two each for you and your spouse. The bristles *might* be firmer than what I remember with the name brand heads.
