We have used these corded Norelco razors for many, many years. They are dependable and do not need to be charged all of the time. We prefer them to cordless razors. The holding charge gets shorter and shorter on a cordless razor. We also prefer taking it apart and cleaning it to washing it. Washing a razor does not clean out facial oil from oily skin, and it becomes clogged and unusable.
I was amazed at how quickly the Norelco 6900LC that I recently purchased gave a smooth, clean shave. I find it more efficient than using the blade, which I won't go back to.
This is a really good electric razor. It has really good speed on the blades. I got rid of my last razor because the head speed was too slow. It makes the cutter pull hairs.
This one has a really smooth cut. Only thing lacking is a pop up trimmer.
