After years of shaving with cream and a razor, it's a pleasure to cut down on the time and mess by using my electric razor. It fits neatly in the hand and is a breeze to use. My only caveats are that the trimmer is narrower than my previous electric and that cleaning the heads is somewhat difficult (though I hope to get better at it over time).
I got this shaver when the head-holder of my father's 7110X eventually wore out. After he passed away I continued to use his shaver because the gears in my 7100 had worn so much over the year that one of the heads would no longer turn. Yes, I use my Norelco shavers for many many years...until they fall apart...then I get another Norelco.
Pros: with proper use and care will last for many years.
