By a whisker past the 5 stars

Visually, the device with the black-chrome appearance and the golden conclusion to the blades a good impression. The thinning shape in the center is first of all used to, but the device can be quiet and very secure grip in your hand. The essays are made of plastic but stable, rest firmly and do not act unduly cheap. Scissors and comb are in the price range sadly usual on the quality of a 1-Shops-Grabbeltisch. The included carrying case is a nice gimmick because no holder or Einrastmöglichkeiten are present, the individual components are only in it just as cluttered as in a usual case.

After about an hour of charging, the device holds less than two hours of use. That's a more than decent record. By the end this is the trim performance does not decrease. The battery level is indicated by a corresponding Leuchtiode.
The cutting length is adjusted by a wide rotary wheel well responds to thumb pressure. Really great: the length (0.5 to 23 mm) is displayed in a corresponding number in mm and thus does not hide in the user guide or becomes pure empirical value. The device is in operation comparatively quiet, but the Turbo Boost increases this noise level noticeably. Neither the beard even when trimming sideburns, I could see an added value through this additional function here.

The Philips HC7450 / 80 is a great device and beats my previous Remington to a good length. What is particularly opposed to this is the reduced cleaning effort thanks to the used titanium blades (no oils!) And not clear his attitude could trim the length.
What stands out is negative for this price to cheap accessories, the not mature carrying case. There remain really good 4 star.
