I concur with Jackklas, I have the NYC chain and U lock. I also have the Evolution Mini and 2 different Krypto cables. It is my opinion that Kryptonite makes a far superior product as compared to other bike lock companies(Multilock makes beautifully engineered padlocks). Their first class locks are definitely not for everyone. I am a NYC Locksmith and I don' t sell Kryptonite yet i find myself buying their locks every time. Just as with any purchase you make, a little investment in time should be taken to research and compare. For some people purchasing a new lock is emotional and they buy the biggest and meanest looking lock there is and that is Ok if it makes them feel safer. Ultimately, security is a state of mind and relative to your environment.
