These are by far the best replacement brushes I have tried. I really like the original brushes and these are just as good. I've tried several other third party options and they always feel like wire brushes, not this one. After that, my teeth are clean and my gums don't get rougher. If you don't need "BrushSync technology" (the bottom is visible in the picture - no ring, no chip), then at this price point you'll be hard pressed to find anything better. I have a good SC toothbrush at home and an SC compatible electric toothbrush that I use outside of the home and these brushes work with both. They are individually sealed and each comes with a head cap. I've been using them for about a week, I'll update if anything changes after 3 months.
