Toptheway Toothbrush Replacement Heads Compatible with Philips Sonicare C1 C2, Plaque Control Electric Toothbrush Head for ProtectiveClean 4100 5100 5300, 10 Pack

These replacement brushes are better than the Sonicare brand version in my opinion. I've been using these for the last 5-6months and just love how the feel and work on my Sonicare Flexcare brush. The heads fit perfectly onto the brush handle. The brush's bristles are longer than a typical Sonicare brush head, which I prefer. And because of this I feel I'm getting a deeper cleaning. There's also an indicator strip to let you know when it's time to replace it. So, if you're looking for a good "soft" replacement brush head for your compatible Sonicare toothbrush, this is the one. You also get a lot of value for your money compared to the brand name. I spent under $18 on a 10-pack. That's less than $1.80 per brush head. I now have enough to last me over 2 years and all for under $20! You can't beat that!! I'm super happy with this purchase and plan to buy even more since this is the perfect soft replacement brush head for me.

Great value easy to install for seniors and comfort no complaints. Very quiet as you can see no damage to gums. Cleans teeth well.

These brush heads are a great, lower-cost alternative for your toothbrush replacement. I have a ProtectiveClean 6100 toothbrush and these fit very snugly onto the shaft of the toothbrush. They don't snap fully down to the base of the toothbrush like name brand, but they work just fine with the little gap. It is a little difficult to get them on/off, but for a reduced price, it's worth the struggle. As it's recommended to change your head every 3 months, you can definitely show signs of wear toward 2.5 months, but I'll push it to the 3 month mark or 2.75 months. If you bear down while brushing, you may see faster wear on these bristles. As promised, they are soft and are comparable to other heads with soft bristles. I've never had any bristles fall off with this product.

I will continue to purchase these toothbrush replacement heads. So much more economical than the brand-name brush heads and they work just as well. My husband and I both use these and they fit the Sonicare perfectly.

While it does not 100% fit 4100 model because of tiny gap between the toothbrush and the head, it is good enough and works fine. Good alternative for overpriced original replacement heads.

Affordable enough to replace frequently. They fit well, the vibration is the same, and they have comfortable bristles. The shape of the head is the same as my diamond clean (also good but more expensive). I feel like I have a new toothbrush.

They are ok. They don’t last as long as the name brand brushes. This pic is after a month use.

Fits as described. Good quality as well.
