Despite its plastic design it seems fairly durable. It can be used with or without the comb and can be set to anywhere between 1mm and 10mm. Before I used it wondered if it's suitable for slightly longer beard but it appears that it can only trim beard to 10mm, which is not a huge issue for me but it might be for others. The main strength of this trimmer for me is the battery that can easily last me up to 2 weeks! #BuiltToLast #BackstageWithBraun
