Better than any other padlock!

Each padlock with key is using the right tool by a professional to crack and although most of combination locks are little more than an alibi.
But this one has very puzzled me: makes a very solid impression (most with a Flex or liquid nitrogen to crack) and is the best that you can open it easily even in total darkness.
Of course, however, you should not be observed (same as with a pin input) when opening ... ;-)

Supplement for half a year use among some quite violent conditions, for example in a box on the bicycle (violent shock and vibration also little wet):
Still works well, as the first day!

Rarely so clear it 5 stars as here!
