8 Best Beard Trimmers (2025): Full Beards, Hair, Stubble

A beard grows about two or three millimeters, depending on who you are – the eighth inch per week, on average. So it can take a long time to test the beard.
In general, we test each beard list as soon as a beard grows enough to get a good trim – using at least a cut length. Weight and balance is important, as well as the ability to reach the embarrassment of embarrassing areas around the neck. We check the TRIMMER’s ability to work as a sting, either for steel or on the neck.
Our test is achieved for the success and easy use of any attachments, and we check the manufacturer’s claims about the battery life and energy. We also verify professional haircuts, especially to verify durability and reliability claims between brands and models.
Tester Matthew Korfhage has a rough and angry hair, with a mind that appears on its own. Tester Andrew Williams has a relatively complete beard, with straight straw. We have tried to reflect any possible problems – we get to know thick bristles, for example – in our reviews, so that you can make sure of the best possible trim with the least voltage. We may run a blade in a broom for horses, to test the engine power, and the possibility of amplification when facing a complete thick beard.
