Its really too bad that a guy has to replace the U bend, replace the flex, buy better quality gaskets, buy different clamps, and still pray that the SD's will work. I guess that is why we say "you get what you pay for".
They were designed like SLP's which also has the u bend. The u bend only needs replaced if you are dropped or dropping.

My flex is fine, my gaskets are fine and I only replaced the 3" clamps. Mine work great. I'm not complaining.
