My hygienist actually asked where I got these because the bristle stiffness feels like what she uses in the chair. Popped it on and the fit was snug with zero wobble, which is more than I can say for the cheaper heads I've tried.

Swapped out my old head for this one and the difference is noticeable right away. The bristles feel just like what I get at the dentist's office, and my teeth are noticeably smoother after just a couple of uses.

The fit on my dentist's tool was perfect, which surprised me since I've had trouble with off-brand heads before. The polish it leaves on my teeth feels just like after a professional cleaning, and the seal is tight enough that no water splashes back in my face.
