The beard grows about a millimeter every two or three days, depending on who you are, on average one eighth of an inch per week. Therefore, testing beard entrainment can take a long time.
Usually, once the beard has grown well enough trimmed, we will test each beard trimmer – with at least two cut lengths. Weight and balance are important, and the blade’s ability can also reach awkward areas around the neck. We check the trimmer’s razor function, whether it’s bald or around the neck.
Our testers checked any accessories manufactured and verified the manufacturer’s claims regarding battery life and power. We also use professional hairstyle checking, especially to verify claims of durability and reliability between brands and models.
Tester Matthew Korfhage has rough and angry hair and looks like he has his own mind. Tester Andrew Williams has a relatively plump beard with upright stubble. In our review, we try to reflect any possible problems (e.g., bothering with thick bristles), so you can determine the best trim with minimal effort. And, we might put blades into a horsehair broom to test the power of the motor and get stuck in a slump when facing a thick beard.
