Does not work
I have the Philips Norelco Shaver 9000 series and these replacement blades do not work. They attach perfectly but when I turn it on, the sound is very loud and pretty scary to put on the face. I tried it anyway and it did not cut anything. When comparing with the original, they look the same but it does not sit well. I think the thickness is the blade is incorrect although the listing says it fits my shaver.
