I've gone through several other beard trimmers, and was very excited about the features this one provides: adjustability, turbo vacuum, EASY-adjust, ability to use corded OR cordless.However, in practice, I've been very frustrated by this one. Adjustability was fine. The easy-adjust ring was nice. It functioned great plugged in or not. The problems I encountered were:1 The swing-out door to empty the clippings broke. It's cheap, and has barely any material supporting it. It's not like you can just tape it closed, because you need to be able to open it.2)The spring-loaded trimmings hatch stuck open, and lost its spring. So, even holding the clippings-door closed, trying to "make-do" and not have to discard this so soon, is very frustrating because the trimmings don't get captured - they stay at the top and spillover the trimmer.3)The turbo has no extra sucking effect. It's useless.4)The turbo is too easily turned on by accident.5)The turbo is LOUD.
