Not so good, I like that you should clean it under running water not him, but only with the supplied brush. Only the shear blades can be removed and washed.
Now to the problem of durability: The shearing blades are driven by a small motor. This turns a small, round metal pin, to which a metal part is attached with balance to allow the right-left movement of the shearing blades. This metal part has simply replaced with me from the pin. It is simply plugged into a round hole in a round pen, which rotates. Mir is incomprehensible how this could keep ever so long ...
Another small negative aspect: In order to get an extended warranty for Philips, you have to register the product using the serial number. It is not to be found with the instructions on the site, I had - like many other reviewers - call for service, order to get it at all. It is located on the way, the back panel, just under the Philips logo. In my case:-NL9785AD. 6 (Something like this!)
Too bad that the shaver has not kept with me, but I'll exchange it, because I have found no better, despite an extensive search.
