I like not all of Philips, but the razors are really good! This part shaved really thoroughly and gently (always shave with Philips) and nice and quiet. As did my old equipment (HS 970) against right wheel. However, this device I had a good 15 years. I also like the cleanability under running water! However, what bothered me when Philips HQ7390 and annoyed, was the terrible packaging. The cardboard packaging is indeed OK, but this plastic crap where the device was sealed is not,! If only to open with scissors! This type packaging I hate like the plague! Had thought that at least is a nice case going sadly wrong :-( But ultimately the function is indeed crucial, and will work out 100%, therefore also 5 star! ... We can only hope that the device by also keeps many years.
