Review on XG 1150 Speed 10 42T Bicycle Cassette by Scott Gendron

After several weeks of trying to index this, I realized that the problem is in the cassette itself, which vibrates. It happens. Everything that is produced is simply made and therefore not always perfect. The problem is that I bought it online. What should I do about it now? My returns window closed a month ago. The seller is under no obligation to do anything about it. SRAM won't do anything. I may have "saved" a few dollars, but now I have to spend 120% more to get something useful. I'm sure "thing" is fine. The one I took off the bike worked well before it got too worn out. This one doesn't work. But I'm sticking with it because I've connected to the LBS network instead, where a hardworking mech would kindly take that junk off my bike and put a working one on.
