It makes a major difference!
I've owned a Braun shaver for 2 or 3 years. It gave a great shave, but gradually and imperceptably the quality of the shave declined.  It was taking longer to shave and even then it wasn't that great a result. Well, DUH! The blades had blunted after literally 100s of shaves. Foolishly, it never dawned on me to think about replacing the blades, until I finally read the note on the box of cleaning liquid.  I ordered the Foil & Cutter Block from Amazon and it arrived quickly. I'm not at all techy so I wondered if I'd have trouble fiddling with tiny screwdrivers etc. No need to worry; you simply pull off the old one, pop on the new one, snap on the new foil cover and start shaving.  I noticed the difference immediately. A much cleaner, quicker shave. If you own a Braun shaver and haven't replaced the cutter in 12+ months, I strongly suggest you do it now.  It's like getting a brand new shaver.
