Master Lock DialSpeed Padlock: The Lock from the Future
Who doesn’t remember using combination locks at school or at your gym? Well it looks like Master Lock has taken it upon itself to push the old combination lock into the future, thanks to its new padlock, which features an electronic interface.
The Master Lock DialSpeed Padlock has a light-up interface where the combination wheel should be, and it allows you to program multiple personalized codes, as well as setting up a permanent master code if you should forget your code. It has a boron carbide shackle, a wide metal body that’s easy to grasp and easy to open with one hand.
The DialSpeed Padlock sells for $25(USD). The only real flaw I can see with this is that it is battery powered, though the battery should give you five years of service before needing a replacement.
