Bought this brush after doing quite a bit of research. Several other people in my family had and loved it. Best brush for the money in my opinion.

This particular toothbrush head fits the old Braun electric toothbrush that I own. The head's last a long time and the dual action is just what I need to clean and help remove plaque.

I bought this first anticipating the Oral B Advancedpower 950TX would work,of which was writen about/reviewed.hopefully I can remedy the brush situation But have absolutly No problem with the replacements still in the package they came in. They Do sound like Winners to me.
Hopeful

I love my Oral-B toothbrush and I loved it even more once I found these refills for it! While I had gotten used to just the small, round head (and my regular dental check-ups have been better since I began using it!), I think that this head does an even better job. It still has the spinning round head, but next to it is a head that makes it more standard toothbrush shape and size that moves back and forth. I feel like I'm getting twice the cleaning every time I brush.

Items didn't fit my product. Some problems with return/refund. Merchant finally made things right. Bottom Line- Buy stuff like this in a physical store.
