Not as good as the head that ships with the brush,
This review is from: Philips Sonicare HX6013/02 ProResults Standard Toothbrush Heads - 3-Pack (Personal Care)
I had the original brush on my Sonicare for far longer than recommended, nearly 6 months in total. However it held together well, didn't spread too much and was perfectly fine nearly up until the end of its life. I replaced it with a set of these, and I am not so impressed. These brushes are narrower and shorter, and they have already started to fray and spread. I don't know if I'm being too forceful with them, but they just don't seem as long-lasting. However, the size is perfect for getting the back teeth, or if you have a smaller mouth.
