My go to heads. Wife and I use different heads. Her gums are more sensitive. Mine, not so much. These are for strong, healthy gums without sensitivity.

Makes brushing easy. Better for teeth and gums. Leaves them healthy. No hard brushing.

Expensive, but outstanding replacement brushes for Sonicare product. I actually like them better then the original brushes that came with the toothbrush.

To save money I had been using off brand replacement heads but decided to go back to Sonicare brushes. There is a huge difference in how they clean your teeth. After first brushing it felt like I had been to the dentist. I found out that these are worth the price. Bought two kinds and this one does whiten your teeth.

W3 covers more area than previously used C2 brushes.

Compatible with my Philips Sonicare that I've had for a few years. It works perfectly.

These seem to be making a difference compared to the smaller brush heads. They are more expensive, but hoping the investment will be worth it.

My previous toothbrush was an Oral-B with the round head that oscillated back-and-forth. With a new Phillips I had trouble getting used to the different motion, which is vibration. It came with a brush head quite a bit smaller and softer bristles. These new replacement bristles are in fact a little larger, and I think the bristles are not as soft, which I prefer.

I’d just bought the new Sonicare 6100 toothbrush at Sam’s, and decided to get replacement heads at the same time. This was before using the toothbrush. These heads are curved/pointed at the top end, supposedly to get at hard to reach areas between teeth. But when using these to brush my teeth, toothpastes flies all over. I have to lean over the sink to avoid making a mess. The bristles are also actually pretty hard. I prefer a softer brush. I would not buy these again, but to each his own.

Brush heads were advertised as universal fit, but they didn't fit.
