Inferior product
I had originally ordered this off-brand replacement head in March of this year.  It was less expensive than the Norelco brand name item, but I figured I would give it a try.<br />When it arrived, I installed them in my Norelco shaver but it didn't work.  To me, it appeared that a prong on the head was bent, prohibiting the blade from rotating.  I returned it with no problem and a replacement was sent to my temporary Florida address in early April.  I, however, was not there until 5/3/22, when I actually received it.<br />I put the new blade set in this morning (May 13) and that, too, does not work properly.  With them installed, the shaver starts and stops and when operational, it does not even remove whiskers.  And now, it appears that this item is beyond the return period.<br />Clearly this is an inferior knock-off.
