Do not trust the title, these brushes are copies! My Oral B brushes are made of a denser plastic and there wrote Oral B above, which is not the case of the latter. It would be good that this be clarified, not that this is sold as branded brushes Oral B. So it is for me to misleading advertising, hence my note.
After the shape and design are identical, the brush is therefore well suited. See it on the length because the density of the plastic is lower and the bristles of the brush appear softer me.
