Mastercraft Dialspeed Padlock
Looking like something straight out of Tron (do the Grid’s residents go to the gym?), Mastercraft’s Dialspeed is an electronic substitute for the humble combination lock. While there are less combinations (seeing as how codes are composed of up, down, left and right commands), length of passcodes more than makes up for it – as does ease of use. Battery life is approximately 5 years, and the centre indicator warns you by changing colour. Just program in a Mortal Kombat fatality command and you’re all set.
