Very similar to the original brush head.
very similar to the original brush head. The wrong model was bought LoL. I found out that it is the model that my roommate brought recently. (shown in the image) quality brush head, so I gave it to her, she likes it very much. (there is a little difference in the image between these two brush head in the image because she changed to the original spare brush head recently.)
