They may well have had some issues back in the stone age but I'll buy Kryptonite every time. The missus and I have three. We use the motorcycle chain-type lock to secure her "station bike" to the railings outside the flat and she uses a New York for the station. I have a fahg and swear by it. If it's getting a bit sticky (you'll know when) then just fill the holes with a spray lube and it will cease to be sticky.

Problem solved.
