A light on the blade – Paw pads are dark and the fur between them is darker. The LED puts light exactly where you're cutting, which is the whole reason this exists.
Runs an hour and a half – A 500 mAh battery, charged over USB in 1.5 to 2 hours. That's several dogs, not one paw.
Tells you where it's at – A small display shows running, charging and fully charged, so you're not guessing before you start.
Washable body – The maker rates the whole thing for rinsing, not just the blade.
16 cm long, 3 cm across – Pen-shaped, so you hold it like a pen rather than a hair clipper.
Cleaning brush included – The small things that stop a trimmer clogging after three uses.
