For me, the smaller size Babybliss is more practical and easier to maneuver... i consider this to be an advantage. Lithium ion battery provides for an extended battery charge. The smaller size is easier to move/control when trimming your beard or hair. Just a personal preference.
Panasonic quality replacement parts.
Excellent 2-in-1 grooming tool that is portable, has good battery life and is a pleasure to look at. Provides satisfactory shaving (not as good as with razor blades, but good enough). Shaving tool is not designed for shaving hair on the face or head, according to manual (only to be used below the neckline). Advertised runtime is 80 minutes, which should be enough if you maintain your hair regularly. It takes approximately 60 minutes to fully recharge the battery. Trimmer head is adjustable in 2mm increments, from as short as 3mm to as long as 11mm. It is water resistant and can be used in shower or in the bath, provided it is not plugged in.
