If numeric combinations aren´t your thing, meet the sleek and sturdy Dialspeed Padlock
by Master Lock. Whilst traditional padlocks require a number
combination on a physical dial, the Dialspeed operates with a series of
arrows, not numbers, it focuses on directional combinations using a
electronic directional interface. In case you forget the correct
directions, the lock also has numbers and letters so you can set a name
combination for example. Up to 3 codes can be programmed in, so the same
lock can be used by different people. It includes a battery good enough for
five years of life and a low battery indicator. No more memorizing
numbers, but you still have to know your left from right. watch the video
