Works well enough for me
After experiencing several after market disasters from trying other brands of cutters this set of cutter blades work well enough for me.  They do give a close shave and float on my elderly face decently.  These do have a different style frame where the cutters spin in.  To be specific. The outside frame does not have the same notch pattern as the original.  This may be due to Norelco supposedly upgrading their cutter design that happened several years ago.  Maybe in that revision, they may have changed the notch pattern.  The circular frame does seem to catch and stay stationary when inserted and the plastic keeper ring is snapped in.  I was concerned it would not.  These spin quietly and don’t chatter like crappy competitors.  Some reviewers are not getting a nice of a shave as I am getting.  That may be because I am older and less “T” flowing.  Another reason is that you have to look for the notches that are 180 degrees apart and insert them correctly into the cutter head frame and insert them to where the notches will catch and stay put.  Then you insert the plastic keeper ring.  If you don’t do this, the cutter frame could spin with the cutters or be out of alignment not seated properly, giving a lousy shave.  This would be like a cars tires out of alignment.<br /><br />The bottom line is that these work fine for me, it just may take a few more swipes across my face than the originals.  I have time for that at this lower price.
