There have been several failures with this chain. If you have one please inspect it carefully. The chain cracks at the pin holes. I saw a chain two weeks ago that was cracked almost every fourth link. This is the second one I saw cracked this year. My chain (being used on 10 speed record carbon) seems fine with 1700 miles on it, but the ones that have broken had 600 or less miles on them. I researched the internet and found several other similar complaints.
Be careful.
