Doesn't work.
This is a nice idea, but these do not fit my Sonicare. The bottom needs to be hollowed out further in order to accommodate this section of plastic at the bottom of the device. Unsure if the seller used a different model to operate their design off of, or just didn't do their homework, because regular Sonicare heads have the clearance for it and advertise fitting all types. Returning.
