Review (1/5): Severe design flaw
My 9170XL is only 7 months old, and it has fallen apart twice already due to a design flaw. The hinge holding together the heads to the body is made of a rapidly rusting metal that stiffens and breaks off. For such an expensive shaver, one would think the company would spring for a non-corrosive hinge.
The shaver, after two weeks (as it says in the instructions) gives me a very good shave. If only it wouldn't keep falling apart.
