Master Lock is a master joke

I had ordered me two of these castles. With a four-digit number
and an increased level of safety I thought to have made a good choice.
The locks prepared but after only a few months a few problems:

- At temperatures below zero the locks (combination) can easily freeze and then can no longer be opened.

- The combination of numbers can be very easily adjusted by mistake.

- The lock can be opened with a bolt cutter by blink easy.

The set numerical code of a castle had disguises himself and the castle was no longer open. With a simple bolt cutters to open was a breeze.
The bracket provides here no resistance.
