i hate to say it but this looks like a user error. im pretty sure you just over tightened it. i have this filter and i love it for the price im actually thinking of getting the cfs700 since it comes with a uv light some this happened to you though

After seeing the pictures of the break around the tightening lug, I changed my mind.
Sorry man, but that looks like classic over tightening.
I agree that if thicker, better grade plastic were used you probably wouldn`t have had an issue.
But, you would have paid allot more money for the filter.
Not really a case of you get what you pay for, more like, if your going to go cheap, you really need to be careful.
