I've been using KMC Missing Links on Shimano 10sp for a few years now. They make replacing your own chains an easy task. I also carry it in my saddlebag along with a small chain tool in case I ever need to fix a broken chain along the way. When I switched to Shimano 105 5800 I switched to these 11 speed lefts. I don't take my chains off to clean them, so not being able to reuse these 11 speed links doesn't bother me. They cost almost three times more than 10sp links so I'm hoping the price will go down as 11sp gets more popular.
