I bought the QT4090 to allow the possibility to be able to have the like-supported 3-day beard and a longer beard trim. Both tasks are done brilliantly. The exhaust is very convenient. Not 100% of the hairs are sucked As reported in other recessions, but the few that go wrong do not bother me. The trimmer is supplied, can be handled equally well and delivers the expected results. The included travel pouch is practical and always in use when the trimmer is in the luggage. The fixed 3-day beard attachment is delivers an extra that I do not necessarily need as the setting to 3 mm with the standard attachment just perfect results. To have the battery life is sufficient in my opinion, because I get along well even over a long weekend so reloading without the trimmer (at 1 x shave / day). To clean: Very simple - it must not be taken to be able to empty the collecting chamber. The small enclosed brush I use only for cleaning the collection chamber when I pick up even the cutting attachment and Purify. This "big" cleaning I make biweekly and see no need to increase the frequency. The guarantee When will the QT4090 registered within three months of purchase on the homepage of Philips extended by one year - then I saw no downside, I made this offer gladly use. The serial number is needed in the way of Bart collecting chamber (4 digits). So all in all a very good product with which I am sometimes very satisfied.
