Title: Imitation? Beware!
Review: Thought I'd add my vote to the many reviewers before me: this product did NOT perform as well as the original heads that came with the brush. While these do seem to brush my teeth well enough, every one of them (am now on # three out of a 4 pack) have regularly pinched my lips and tongue while in use. And the last brush wobbled and fell apart while in use. Will not purchase again.
