Futulkyus Replacement Toothbrush Heads for Philips Sonicare C1, C2, ProtectiveClean 4100, 5100, 10 Pack

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.

Work great and much more affordable than the name brand.

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.

Great replacement heads for my sonicare tooth brush excellent price good look and feel but I will be getting the one that goes with the machine when my funds are up

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

It works ok but does not stay in one place over time. The brush head ends up moving up or down so you don’t get the optimal brush per second that makes the toothbrush effective.

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

I actually like these better then the original. They are more firm and do a better cleaning!
