Good, but not superb
Given that it's advertised as trimming between 0.2mm and 25mm I was disappointed to find that there is no "adjustment" as such for length, and so I can't achieve my customary medium stubble look; my chin can either be more or less smooth, or very furry. The smallest "comb" though marked 1.5mm in reality leaves the bristles much longer, and there's no in between.
Everything else works well, though a less miserable carrying case would have been nice
