I was afraid installing the new heads was going to be difficult, but I was astounded with how simple it was especially after reading some reviews written by other customers. The heads literally dropped right into place & I was back to getting a clean shave within minutes. It was like using a new razor again. Thank you!

Have gotten off brand heads before and they always pulled my whiskers. I got used to it but decided to try the name brand ones, and the difference is night and day. My whiskers don't get pulled anymore. If you whiskers get pulled regularly you need to get a new set.

Works great after some fixings I had to apply.Housing for the blade will not fit Phillips 6000 series. You must file down the teeth on it.

These are great! They’re sharp! Instantly transform your legacy razor into a new again razor! I’ve tried the cheaper off brand alternatives. Believe me you get what you pay for. They’re horrible. Don’t waste your time or your money! Save your face!!

Made for the razor by the manufacturer. Not much else to say. They work.

These make the shaver work like new again. I did not notice how bad the old blades had gotten. Thought the shaver was worn out and I needed a new one. Should have bought these a long time ago.

This set of replacement heads was perfect for my older model 5200. These are exact Philips replacement parts. I got the best shave in a year with these.

Fit and function are good.
