Fantastic quality from SRAM as always. Haven't had to deal with any breaks thus far, and installing it was easier than putting butter on toast. If you're in the market for this type of chain, this is the one to go for.
I love Eagle, and the best way to ensure you don't have to buy a new $400 cassette is to replace your chain before it gets too stretched. I typically spin at a higher cadence so my chains tend to last, but I still replace them every 600 miles or so on the mountain bike just to extend the life of my cassette.
