The steel-bladed Wahl Performance trimmer is ideal for tricky tasks such as trimming beards, goatees, necklines, sideburns and body hair. It has multi-position guide combs that allow you to adjust the cutting length without changing the guide comb. The trimmer has a soft-touch grip for added comfort. It is battery operated (batteries not included) and has a recharge time of 10 hours. Although it is not water-resistant, it can be used safely in the bathroom.
