Review (5/5): Worked out great! Glad I went for it.
Somewhat Leary about the fit and quality before ordering but the price was good so I went for it. Very pleasantly surprised! They fit my Sonic and perform great! Shame on a good company lie Oral-B for not making the replacement heads anymore after so many people bought their Sonic Vitality brush. I have purchased Oral-B products many times but will definitely think twice about it next time!
