PHILIPSReplacement Shaver Head for Series 9000 & Prestige S9000 Precision Blades

They do shave a lot better than my previous heads that were SH70- the SH heads without the two protruding nubbins (SH90, 91,70,71,60,61) are interchangeable between various shavers that use them, so you don't have to stick to the lower-end heads if you have a different shaver. These blades are original and new. They do shave noticeably closer than SH70, maybe even too close. For best results you should run them for a few minutes dry before first use to get rid of any oxidation, and the lubricate them before first use. The also have a break-in period of about a month after which they shave much better than straight out of the box. Also to extend their life do what I did and number each stator and its corresponding rotor with a knife or needle, so that they are a pair and go back together after each cleaning- this will ensure that any surface imperfections of the rotor are conformed to by its corresponding stator as the head wears and are not propagated to the other pairs (this is what they call "self-sharpening", the blade wears in a way that makes it conform better to the cup, and cup wears in a way that conforms to the blade). Alternatively, when cleaning remove and clean the pairs one by one so they don't get mixed up. Also washing the shaver with a Waterpik makes it shave really well and I highly recommend it.The SH50/51/30/31 have the two nubbins and won't fit shavers that don't have space for them (and SH60-91 might not work in some of these shavers due to the lack of nubbins), and the RQ heads are a bit smaller than SH.

After two years I changed blades on my Norelco, big difference.

It is working like my original blades, great shave and comfortable

...let's just say they seem a bit sketchy. From a third party vendor. Arrive in unsealed box that appears to have been opened. Sealed blister pack card inside says "Philips" in big letters the front. But all the tiny text on the back is in Russian, I assume, since the cyrillic alphabet is used. (Box text is in English but says made in Netherlands) So let's just say the origins are pretty questionable. Still, I examined them closely and from what I can tell, they are real deal and work well, running quiet and providing a close, comfortable shave. And about half the price of Amazon-sourced Philips heads and blades for this model series.

More expensive than it should, even when it’s OEM with exceptional quality assurance. I have to yet to come across a replica that matches the quality of these. Get the real deal. Your skin will thank you.

My grandpa has been using the Philips Norelco SH91 Replacement Shaving Heads for a while now, and he absolutely prefers them over replacing his whole electric razor. His old shaver was still working fine, but the blades were getting dull, and it wasn't giving him the smooth, close shave he used to get. When I suggested replacing the shaving heads instead of buying a whole new razor, he was hesitant at first, but now he’s so glad he made the switch.The SH91 blades have completely transformed his shaving experience. They provide a much closer, more comfortable shave, and he says it feels just like the day he first got his shaver. The blades cut in every direction, so he doesn't have to make as many passes, which makes shaving quicker and easier. Plus, since the blades are self-sharpening, he's confident it will last a long time before needing another replacement.For my grandpa, it's not just about getting a good shave—it’s about keeping his favorite shaver in good working condition without the hassle of switching to a new model. He finds the replacement heads easy to install, and now his razor is performing better than ever. He’s a fan of the convenience and value, and I’d recommend this option to anyone who wants to extend the life of their Philips Norelco shaver.

It works!!

This is the first time I've replaced the heads of my Philips s9000. Expected good instructions from Philips. My bad. I carefully disassembled old heads to confirm new parts fit. Had to guess at assembly, though. Initial shave was best in months. So my guesses must have been lucky. But I will not buy this again as my luck probably will not be persistent.
