"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 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."

I would 101% recommend these guys
They are extremely knowledgeable and helpful. They go out of their way to help and ensure you get the correct product for you needs. I can not thank them enough, if only more buisness cared so much.

Flawless experience
My queries about the products I was looking at were answered quickly, and the person I spoke to was happy to delay despatch of my items (at my request) to arrive on a specific day. Excellent customer service.
