Review on 🪥 12 Pack Electric Toothbrush Replacement Brush Heads Compatible with Philips Sonicare ProtectiveClean DiamondClean 2 Series Snap-On Toothbrush 4100 5100 C2 C3 W2 HX9024 HX6064 by Heather Davis

I didn't really like these heads. They fit my Sonicare perfectly, but the bristles themselves look a bit sloppy and rough. I kept trying it for about a week, but even though my teeth were very clean, I noticed that my gums hurt a lot after each use. I ended up switching to another generic brand with a smaller head and better bristles and I'm no longer in pain. I have sensitive teeth and gums. If you don't, this might be a better fit for you. Unfortunately I didn't get them.
