Did not work as expected.
I have had my Philips Norelco razor for years and faithfully change the heads every six months.  This time, however,<br />I was not able to get my customary close shave, which would leave my face and neck feeling smooth to the touch.  I reseated the heads thinking that I may have installed them incorrectly but to no avail.  I ordered a new electric razor of a different brand at half the price which works great.
