With a high-performance 9,800 cuts per minute linear motor, the Beard Trimmer for Men ER-SB40-K quickly and comfortably grooms beards, mustaches, and hair. It features an ergonomic, rubberized grip and 19 adjustable clipper and trimmer settings. The ER-SB40-K offers an improved cutting edge with ultra-sharp stainless-steel, hypoallergenic wide tip blades to help lift, capture, and cut neatly through even the unruliest hair, including whiskers that lie flat on the skin. The rechargeable trimmer can be used cordless for up to 60 minutes or plugged into any AC outlet for extended use. The men’s hair and beard trimmer is 100% washable and cleans quickly under running water. Like all wet/dry shavers and beard and hair trimmers, the blade should be replaced when dull for the best performance. The ER-SB40-K includes a comb attachment, cleaning brush, blade oil, AC adapter/charger, and universal voltage for international travel (AC 100-240 V).
