You get what you pay for
Yes, they fit the Sonicare and are the same size as the previously available compact brushes, but they do not have the same cleaning ability. They are too soft and the bristles really don't seem very effective. If you are like me and need a smaller toothbrush head, you are probably trying to replace the awesome compact heads Philips Soniscare used to offer, but these just don't cut it. I'll use these for now, until I can find a true replacement, but won't buy again.
