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

Same quality as more expensive Oral B option for a much better price. They last for quite awhile too.

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.

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.

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

I recently purchased the replacement heads for my Philips Sonicare electric toothbrush. The product, while functional, left me with a few reservations. I'm giving this item a three-star rating based on my experience. Upon unboxing, the first thing I noticed was that the replacement heads did not have the same premium feel that I have grown accustomed to with Philips products. The material quality seemed to be a notch below that of the original heads, lending a cheap feel to them. It's understandable that replacement items need to be cost-effective, but a slightly higher standard of quality wouldn't go amiss here. The bristles were another area of contention for me. They were noticeably softer than the ones on the original brush head. While this might be suitable for those with sensitive gums or teeth, I prefer a firm brush head for that thorough, deep clean. These softer bristles, in my opinion, don't offer the same vigorous brushing experience. On the brighter side, these replacement heads are compatible and easy to install, making the transition from the old head to the new one seamless. They deliver a decent clean, despite the softer bristles, and maintain most of the features that make the Philips Sonicare range so popular. The heads also retain the Sonicare's advanced technology, which means your toothbrush will still offer you the high-speed vibrations and movements that ensure a comprehensive clean. Plus, they come in a compact package which is a bonus for those with storage concerns. In conclusion, while the Philips Sonicare replacement heads get the job done, they lack the robustness I'd expect from this brand. They feel somewhat cheap and may not deliver the deep clean you're after if you prefer firmer bristles. But if you can look past these issues, you'll find a functional product that continues to deliver the benefits of the Sonicare range. Please consider your brushing preferences before purchasing.

There work great as a replacement for the name brand. They don't fit on all the way to the holder so you have to be sure to get the toothpaste leftovers out. Other than that they are fine
