Futulkyus Toothbrush Replacement Brush Heads for Philips Sonicare, Electric Sonic Tooth Refill Head 4100 C1 C2 G2 Plaque Control, 10 Pack, Black

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

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.
