Review (2/5): Not So Good
These are very inexpensive replacement heads for the Oral-B electric toothbrush. They are much lower quality than the originals. These claim to be extra soft but they seem to be stiff and they hurt my gums. Also all the bristles are the same length. I went back to using an original Oral-B dual action head and they clean my teeth much better. If you want to a lot of heads for a little price then these are for you.
