slower shaving than my old norelco [SEP] i have been a long time norelco shaver user when it was time to buy a new set of series lift and cut heads for my old norelco razor i decided to get the new razor big mistake the new ring smart touch heads are not as good as the old reliable lift and cut headswhy you say to make the head look like it has more surface area and thus should cut faster the norelo engineers reduced the cutting area of the fastest outer ring to squeeze in the two inner but slower surface speed rings in fact the outer ring cutting blades are only mm wide as opposted the the mm width cutter width in the series lift and cut heads the added inner rings actually cause pulling of the beard hairs if you try to shave at the same speed you did with the older modelsby the way the so called cleaning system is a big bother and not worth the extra cost you can rinse the under the faucet just like the older xl models in fact you have to rinse it because of the sticky mess the cleaning system leaves in the razor after cleaning the bottom line in a failed attempt to make a quieter faster shaving system norelco actually made it worse than earlier lift and cut models then to top that off changed the drive pin design so that one can not use the superior heads do not waste your hard earned cash on this sub par norelco product
