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.

Otherwise, the trimmer is similar to the MGK 3245, offering the same 80 minutes of precision trimming on an 8-hour charge.

Braun Beard Trimmer Customer Reviews

As you can see, each trimmer in the 5 Series offers the same power and basic features. They differ only in color and included attachments.

That said, it is possible to remove the guard entirely and use the full width of the blades, which I found gave a nice close shave without leaving the cheeks looking like a baby’s bum. Although, shaving when guard-less can irritate the skin and I found it did scratch a few times. This is a washable cordless beard trimmer so you can use it in the shower so long as you take care not to submerge the unit. The head is washable so you can run this part of the beard trimmer under the shower to remove hairs as you trim. The body of the Braun beard trimmer BT7330 should not be held directly under running water, however.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. 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.
