This is a nice strong and solid padlock. I love the red color. It is bigger than I expected, 3.4 inches. It comes with a four digit combination so offers a stronger safety level. The lock itself is made of nickel plated steel.
It comes with instructions as to how to unlock the original password, set your password and how to lock. Like other locks this lock does not have a reset setting and once you set your password there is no way to reset it. So one will have to remember or note down their password somewhere safe because if you forget your password this lock could be really difficult to break through.
The size is good enough to use on any luggage, bicycle, indoor or outdoor devices.
