The more I use these "gimmick" attachments the more I think the best move is to use the regular heads or maybe the dual action. The stiff flossing points do feel pretty good on your gums but as far as actually mimicking the action of really flossing your teeth, I suspect they are not that effective. Definitily stay away from the heads with the polishing cup. That just doesnt do anything unless you have real dental polishing paste maybe.

I have been using these for the past three years, as they originally came with my 9000 series. Although they say they are floss action, they do not come close to using regular floss, as they can not get all the way between the teeth, and below the gum line. I have had no cavities, and cleaner teeth since upgrading to the 9000 with the floss action, so I guess they do work well.

Great value for a fraction of the price of other electric toothbrushes and their replacement brushes.

This product was used to replace the original brush head that came with my Oral B Triumph toothbrush. I replace the head every 3 months. These work great!

I changed to these brush heads after using the other basic type for years and what a difference. I highly recommend these brush heads - I do see a difference and especially if you brush for the recommended two minutes. Wish I'd changed sooner.
