I've even brought due to the low price of this chain, in order to test times. Any comments regarding the complexity of the QuickLink-chain lock I can not understand completely. The effort to close the castle is minimal and who can not read properly a guide that present enclosed in more than 5 languages and the evidence ignored, which one can not help really. It takes a minute to open the chain and close. Therefore my judgment is that chain is top, my expectations fulfilled!
