Toptheway Toothbrush Replacement Heads Compatible with Philips Sonicare ProtectiveClean DiamondClean C2 G2 W 4100 5100 HX9023 Plaque Control, 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.

This is a great deal for 10 brush heads. I pushed it down onto my Philips Sonicare C1 and it works just fine.

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.

This product replacement may not be the name brand but they do work great. It also fits perfectly on the sonic toothbrush and they last about the same as the name brand if not longer. They are gentle on the teeth.

Individually wrapped, and they fit my sonicare c1 as advertised. Good value for the money.
