Title: Oral-B EB17-3 Won't buy these again!
Review: http://www.amazon.com/gp/product/B00006ANDJ/ref=cm_cr_rev_prod_titleThese are too tight fitting but the 1st one worked in spite of the tight fit. The 2nd one was defective, the inside o ring was loose hence the brush did not spin. Bogus! Can't believe these are real Oral B replacement heads.
