One of the Better Oral-B Generic Toothrush Head Replacements
These are Great Generic Oral B Replacement Toothbrushes.  In answer to the people that gave them low reviews for NOT being Oral B, that's what Compatible means!!!!  If they were original Oral B toothbrush heads, you wouldn't be buying 4 for less than the costs of one.  I had absolutely no problem with these at all.  I had no bristles coming off in my mouth as one reviewer said.  I don't know how vigorous they were brushing, but we used these for a long time and that never once happened to us.  They held up great.  I've tried several different generics, some better than others and these are some of the better ones.
