SH50 / 52 Replacement Heads for Philips Electric Shaver Series 5000 with Sharp Blades, Super Lift and Easy Cut, 3-Pack ( Non- Original Heads )

The original heads wear used for three years and sharper the these. Wheel burn

They work far, far better than the dull blades I replaced. However, they are not up to OEM standards in that they are missing the little leading tab that provide the "lift and cut" action of the originals. Therefore, they don't cut quite as closely as fresh Norelco heads. Can't comment on how long they'll last...I tried them out because I hate paying for new blades that are 1/2 the price of a new razor plus spare heads! Crazy!

Makes the shaver operate slow due to alignment

Low quality.I can not understand why it was rated so high at others review..The heads not trimming sharp and need to go over and over same spot..I lubricate the heads as mention without any improvement.

I bought this thinking that it will fit my shaver and no, didn’t work at all, also quality is not good at all. I had to returned cuz didn’t fit into my machine

Sharp and works great

I've been using the same Norelco electric razor for around 5 years. I bought these blades and foils to replace the Norelco ones I've been using for about a year. I noticed from the beginning, that my shave was not as close as it had been, and the blades were pulling/tugging my beard quite a bit. Nevertheless, I continued using the the new blades and foils, hoping for improvement, which never came. So, I inspected the new blades and foils and found that the hole pattern on the the foils were different from my old ones I kept, just in case I had a problem. Then I decided to mix and match the new blades and foils with the old ones, to see if there was a combination that worked best. What I found was that I got the best/closest shave using the old Norelco blades and foils. Lesson learned, I'll just stick with Norelco replacements from now on.

Shaver head are just as good as Norelco brand at 1/3 the price.
