There are plenty of things to consider when deciding on a beard trimmer, but these are the most important in our opinion (apart from price). Most beard trimmers will come with some guards, but make sure the one you choose has a guard that’s long enough for your desired beard style, especially if you have a medium or long beard. Cord Versus Cordless: Most beard trimmers these days are cordless, which allows you to use them more freely without worrying about a cord getting in the way. Additional Features: You’ll often find a variety of other features in beard trimmers, most of which aren’t essential but are great to have. Many beard trimmers without these work well, but having them can make for pleasant, and in some cases more efficient, use.
