Painful and doesn't work! I wish i could give it NO STARS
I should have figured the price was too good to be true. Although the heads DO fit my new toothbrush, the bristles don't rotate; they just vibrate in place. And there's a yellow plastic circle in the middle that catches on the inside of my lips and hurts. I bought 3 packs of these and they weren't worth returning--went to the trash instead.
