That's why I this nose trimmer (also for ear hair) because of the many positive reviews and bought myself am thrilled. Until now I had a trimmer with round shaving head and a rotating blade. With this device, a renowned manufacturer, I was not happy at all, because I've caught a few hairs.
The Philips cuts contrast very well and fits comfortably in your hand. Despite the low price, the perceived quality is very good. The disturbing hair can be removed easily. Practically, the two towers are to shorten the eyebrows. (Yes, be with age even longer :-()
The blades must not be like other devices, oiled.
My conclusion: I can not say anything yet about durability, but the impression so far leaves me only one conclusion to: BUY.

Meanwhile we write December 2011: The trimmer still trims. The shelf life is thus very satisfactory in my device.
