This is a good set of toothbrush heads, worked realy well with my philips soniccare electric toothbrush. I must say that the heads are a little bit different than the original, so it took me a few days to adapt to the new style... they are super soft, which is a plus for me - avoids getting your gums hurt. All and all i am satisfied with the product, and its in an incredible price range. Hope you like it.
