It's not perfect but it does the job pretty well. So far is the best beard trimmer that I owned and I had many, including Phillips, Panasonic, Brawn and Wahl. The battery last for a long time, so it's perfect if you travel abroad, because with a full charge you can trim your bird three times at least, so you can avoid to bring with you the charger. I do that once a week. Easy to clean, The thickness adjustment is probably the best feature of this trimmer. I can't give it 5 stars because there is a big room for improvement, but I truly recommend it.
