The promise of rattle-free transportation of the lock holds true, or rather, I can now hear my kick stand rattle… But the best thing is not having to constantly check my old Kryptonite lock for whether it was about to rattle out of its holder.
The lock holder is made of soft, rubbery plastic and has a stabilizing metal bar at its back, with holes for attaching it firmly to bottle-holder sockets in the bicycle frame.
The price seems fair for what one gets. I would personally avoid the cheaper varieties of the same brand that have simpler keys and probably will not last as long.
My only complaint is that the lock, due to its weight and many joints, is a bit difficult to handle, but I will probably learn various tricks over time.
