No wires or cables, appears to be stone reliable, you can carry a spare battery set if you are going long but it would have to be pretty long. I charged this system when I got it a couple of months ago and it shows fully charged after a fair amount of riding, The shifter batteries do about 600+ miles but that is dependent on how much shifting you do, The lever batteries are good for maybe a year or two (little key fob batteries)
I would expect electrical shifting to begin to dominate a portion of the market over time, sort of like disc brakes are doing,
