I have been using Philips shavers for just over 40 years and will never use another brand. Totally satisfied. Also recently purchased Philips 3000series nose trimmer, also great.

It's the worst securing system from all shavers I had. Difficult to close, and it breaks easily, i.e. the notches on the red retainer rig are tiny and break off. Worst, when ordering new shaver heads (because thy do not last long either), these retainer rings are not included.
