Philips Norelco SH91/52 Replacement Blades for Shaver Series 9000 (S9xxx) and S9000 Prestige (SP98xx) - Self-Sharpening Precision Blades

Perfect. Shaves like a new razor now. Easy to install new blades

Theses blades are the correct ones for the 9000 series shavers and i don't know yet but it says on the box replace every 2 years so if thats true and theses blades last for 2 years then it's worth it and a lot cheaper than buying a hand shaver of any brand because think about over 2 years buying hand shaver blades in just 6 month you already spent way more than theses Norelco electric shaver blades. I shave dry but you can shave in the shower and the cleaning pods that you get with the Norelco electric shaver 9000 series really get it very clean but i rinse mine with warm water then i use it on the cleaning pod and i don't have to shave for 2-3 more days very worth using.

Works surprisingly well for substitute part (recommended by Philips Norelco).

Not that easy to install.

These are the replacement blades for the S9000, better than the OLDER Prestige blades. Beware, the S91/50 are the OLDER blades, but these are the newest correct S91/52 blades. The S91/50 have purple retainers while these are black. These are awesome.

Bought this as a replacement. Fits and works perfectly.

Very happy with purchase. Able to keep my $200 razor.

Made the razor run like new. Closer smoother shave with less irritation.
