The only thing I don't like is I expected the numeric lock to be permanently attached to the cable on both ends, allowing me to simply insert one end of the cable into the other and locking.  It's not a deal breaker, but you do have to enter the combination, remove the combo part of the lock, and then slide the cable through.  This length is perfect for locking either two bikes side-by-side, or locking an adult bike and a connected trailer bike for a child. I also use it on my bike rack as a deterrent for theft.  Obviously a serious thief will cut it, but as a deterrent for a casual thief, it does the trick.
