Number code is easily "scanned"

But a chain happens to be only as strong as its weakest link and that is, as the previous speaker has already said correctly, only about half as thick as the rest of the chain. So you always drags twice as much weight around than you would need for the same level of security really.

The right hammer is that not even tools and training needed to to pick the lock. Everybody with a little sensation in the fingers creates the knowing quite easily without the code. There are also a video on YouTube. I needed to not 3 minutes did so but never done anything before. Waste of money and very bad image for the expensive leader Abus.

I have removed the Zalenmechanismus to the weak links of the chain and use them now with a reasonable padlock (but not from Abus). This costs just back about 20th
