"First stage attacks didn't touch the chain or the lock. Our mechanical attacks did get through eventually but had to make a lot of noise for some time in order to do so." 
"The Protector range from Pragmasis is perhaps the ultimate bicycle chain lock. The 16 mm links are formed from hardened boron steel and are impossible to bolt crop."
"The shackle on this (the DIB D-Lock) is nice and beefy, with a 16mm diameter, made of a very well hardened S2 tool steel. This is a product that I would consider using."

The Lock Picking Lawyer

"The RoundLock is outstanding, offering excellent security in a small, light package, as well as adding even more value by doubling as a disc lock."
"The 16mm hardened steel shackle of the DIB D lock is impossible to crop by hand with standard manual croppers and can even withstand the largest 42-inch Irwin Record bolt croppers."
