This beard and mustache trimmer was named The Best by the Hammacher Schlemmer Institute due to its superior performance, ease of use, and extra features. Unlike lesser units that left stray hairs uncut, this model was lauded for its ability to uniformly trim hair and provide a more precise shave quality due to its unique head attachments. The Best unit was also praised for being the easiest to charge, clean, and operate. It runs up to 31/2-hours on a full charge and has a list of superior features including seven individual guide combs and four trimming blades. Also comes with blade oil, cleaning brush, and carrying case. AC plug. 6" H. (4 1/2 oz.)
