Toptheway Toothbrush Replacement Heads Compatible with Philips Sonicare ProtectiveClean DiamondClean C2 G2 W 4100 5100 HX9023 Plaque Control, 10 Pack

They work as well as the original at a much lower price. When you get 10 at A. Borgen Price, it encourages you to do what you should do, which has changed them relevantly frequently.

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.

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

Have bought these multiple times and they work great on my toothbrush. Seems to be same quality as the more expensive brands.
