It depends on the needs .....

Everyone should be clear that this lock is not suitable for high-quality bicycles or lonely parking adequate. I think this castle can be cracked with a bolt cutter in a few seconds. Also pick the number combination has a known cost not 15 seconds.

However, similar bike against the Simple driving (no tools required) to "secure" this castle sufficient.

The combination of numbers can be set simply and precisely. Opening and closing works without hooks and clamps.
Although the castle has often been wet in the rain, can be seen nowhere rust. The sheathing is sufficient to protect against the frame paint damage.

The length of the castle borders the options when you connect already quite. Who his bike similar to trees would like to join, should definitely choose a longer variant.
