I heard from a couple of sources that their Sunrace cassettes broke shortly after using it. I was prepared, but I got it anyway since they're the only supplier of a 11-34T 7-speed cassette. Although I was expecting it to break, I didn't think it would arrive in the mail already broken! Two of the smallest cogs spin right out of the box! I contacted the seller through Amazon right away. We'll see what they do to help.
