The desired cutting length can be adjusted easily via a rotary knob. If the hairs remain standing longer than it would be feasible with the standard attachment, you simply fall back on the additionally supplied attachment for lengths from 1.8 cm. Who, however, the 3 mm cutting length of the smaller comb are too much yet, can use the device even without attachment. So far I have always achieved with the device an even result, so have nothing to complain about in terms of practicality.
A cleaning brush and oil are also in the package, but so far every hair- / beard trimmer has survived for years, without being well oiled only once with me. Nice, then, that this accessory is, however, most are it might not need. Certainly the nursing needs of the mechanics but also depends on how often you use the hair clipper.
All in all a good product at a reasonable price, so I can definitely recommend.
