Review title is Similar, fits well [SEP] The four pack of Oral B replacement heads fits nice and snug on my electric toothbrush.  The feel of the brush heads is similar to the basic Oral B brush heads. I am more used to the "Flossing" heads, so this was very soft feeling to me.  They work fine and should last similarly to the Oral B Originals.  The package came torn at the top, as if it were torn from a bigger section incorrectly or sloppily. That dropped it a star.
