I spent 10-15 hours researching and bought 3-4 different trimmers. THIS IS THE ONE. It’s the best I found out of all the top brands and models.

I found the precision shaving head annoyingly small for a full face shave and the foil attachment is only really good for achieving clean lines in longer beards. The precision trimming element is equally tiny, so again, is best left to precise sideburns or neatening up an impressive moustache. After reviewing each of the beard trimmers and multi-groomers from Braun, I recommend the MGK7221 as one of the best waterproof beard trimmers this year. There are slightly cheaper beard trimmers out there but the Braun Beard Trimmer 7 feels like good value for money, earning its place on our best beard trimmer list. It is small, light and easy to use, while the tough blades shave cleanly and feel like they are built to last. This BT3240 offers even more battery power with up to 80 minutes of cordless trimming. This trimmer is 100% washable for easy cleaning.Braun created a great comparison chart to help you decide which beard trimmer is best for your needs. This rechargeable 7-in-1 trimmer includes 5 attachments for beard, face, and body. The NiMH battery provides 80 minutes of trimming on a full charge and recharges in 8 hours.

The Braun Beard Trimmer 3 series is the base model beard trimmer with 20 length settings ranging from .5mm to 10mm. The cordless trimmer offers up to 50 minutes of trimming on a single charge with a full recharge in 10 hours.

To trim your facial hair, set the precision wheel to the desired length and move the blades over your beard in smooth strokes. For longer beard lengths, or to use your men's beard trimmer as a set of hair clippers, attach one of the supplied combs. Alternatively, you can remove the trimming blades and replace them with the mini foil shaver attachment or the detail trimmer head to style your beard with neat edges and detailing. This series of Braun multi-groom trimmers are also great for beards. They offer many of the same great features, like lifetime sharp blades, with even more versatility.
