I will give you this - Norelco is much better in all ways than the competition of Rem*&^%$, etc., BUT I miss just a 'plain Jane' simple corded model, which I have always had and prefer. One can not find a razor now with a sideburn trimmer that has a cord without the gel injection, rechargeable, and other features I do not need.
My father always used a simple 2 or 3 head Norelco which plugs in and I prefer this too. This model is about 85% the power, even fully charged, of the old corded type. I like the grip too of my old one a little better too for some reason - more comfortable. Unfortunately, everything seems to change, including products, and change is NOT always better or good. I would even pay more for the 'old' type I used to have verses this lower power rechargeable.
