Re-usable 11 or 12 speed chain links

You wax your chain regularly, so that means you take you chain on and off your bike a couple of times a month. Most Quick or Power links are single use, do you change yours each time? Do you value your teeth?
Check out the Wippermann Connex 11 or 12 speed reusable chain link.
Simple to instal, no tools needed, just twist the link into a z shape and the links simply seperate.
When fitting make sure the numbers on the link (11 or 12) are right reading when on the lower section of the chain. If your gears jump in the 10/11 tooth after instal, you have the link the wrong way up.
