The manufacturer calls the kit 4-in-1, meaning one trimmer handles four different jobs. The 14 settings from 0.5 to 21 mm let you choose between short stubble and a longer beard. The NiMH battery takes 10 hours to charge, so the easiest routine is to put the groomer on charge in the evening and use it the next day.
AIO3500 suits people who need a simple cordless trimmer for the beard and hair and do not need waterproofing or a pouch. Up to 50 minutes of runtime covers several shorter sessions, and the cleaning brush helps keep the blade clean.
