Replacement Toothbrush Heads Compatible with Philips Sonicare C2 Plaque Control Protective Clean 4100 5100 6100 Electric Toothbrush, 8-Pack Sonic Brush Heads

Can’t beat the price, great project well made - will be purchasing more in the future. Soft bristles

Nice quality with reasonable price :)

Fits my sonic, however the plastic brush covering is very tight that when I pull it off, the whole head comes off sometimes. You have to hold it on while you uncover the brush. While brushing my teeth it stops vibrating intermittently. Might have to buy the original brand. For the most part it fits.

I thought I'd try this least expensive option to replace my Sonic toothbrush. It works just as well as the Sonic name brand brush does. No issues at all.

As you can see in the picture, this item’s hole is a different shape than the Sonicare toothbrush on the right. This results in the sensor lowering the power and making these brush heads pretty useless. Search around and you can find good deals on Sonicare brush heads.

Just as good as philips

I'm really bummed that I purchased these with the toothbrush. They said they were compatible with my sonic toothbrush and now that I am starting to use them the return window has closed. If you put any pressure at all on the brush against your teeth it stops the vibration. These are absolutely Not a good replacement for the actual sonic brand

It came in a small, heavy cardboard box. Easy directions and it fit perfectly on my toothbrush, Sonicare. Great quality and very affordable!! This was a great find for me!
