The Braun BT7441 automatically adjusts the shaving power to your beard length. That's because the AutoSense technology measures the length of your beard. This beard trimmer also includes a Gilette shaver blade. So you can trim your beard, but can also shave your face. The beard trimmer also includes other useful attachments. A comb attachment to create a fade, for example. The battery lasts 100 minutes, which is a long time. Is the battery empty? Place the beard trimmer on the charging stand. The trimmer is waterproof, so you can also use it in the shower. And you can easily take the beard trimmer with you on your travels in the travel pouch.
