Toothbrush Replacement Brush Heads for Philips Sonicare C1 C2 ProtectiveClean 4100 5100, Electric Sonic Tooth Refill Head Plaque Control, 10 Pack, Black

These are great heads. Not too hard, not to soft. And this pack is inexpensive, so I don't feel wasteful changing them every month, or throwing them out when I might be sick. And my teeth keep getting whiter and whiter. Soon my teeth will shine like those stupid laser-beam LED headlights that blind you on the highway!!

These generic brush heads work perfect and way more affordable than the name brand ones. They are compatible and fit perfect on the Philips brush. The bristles are not too soft or too stiff.

I've ordered this same brand in the past and they fit well. These do not fit as snug, however, I am keeping them. They will work well enough.

Works for Phillips Sonic Care 4100. I don’t see a difference between the name brand and this brand. You get a better value from this brand since you can get so much at once.

Work great and much more affordable than the name brand.

Good value. Fits on my sonicare fine.

So far so good. They fit well on my Panasonic toothbrush, unlike others that I have purchased.

Great value. The Sonicare 4100 came with a set of brushes, but these seem to clean better!

The ofashu refills tooth brush are well fit for Philips toothbrush. The number of quantity of 8 items well received.
