Summary: Bought this for my man a few years back, and he's still using it to this day. In his opinion, the functionality of it as a beard trimmer is great; it does exactly what he wants it to do. But, he has one gripe with it (and only one) - the battery life is poor. Anytime you want to use it, you need to charge it up ahead of time. If you charge it on say, Monday, and don't use it, you're out of luck in a few days because it doesn't hold its charge.
