These links are easy to install and run smoothly on my 11 speed Durace chain. Inexpensive too. Make it economical and easy to remove chain when cleaning drive train and waxing.
I converted to wax about a year ago and have gotten good enough at the hot dip process that I don't even bother with touching up a chain with drip wax. Every 200 miles or so, I just swap the chain for a previously dipped chain. But, that means lots of "chain-breaking". IMHO, the "use-once" warning on OEM quick links seems to be a joint statement from the Legal and Marketing departments. But, still . . . quick links do have a limited life. These YBN quick links are an economical way to avoid pushing your luck by using a quick link one too many times.
Compared to the Shimano equivalent master link, this is about a third the cost. The manufacturer of this product says it can be re-used 5 times. Shimano says their master link can't be re-used at all. So, if all you care about is cost, then this master link is the way to go. I've used this master link for about 500 miles and I can't tell the difference between it and the Shimano equivalent. Of course even a single failure would negate any cost savings. Only time will tell.
