Makes total sense. We do this because we honestly get the most asinine claims and had to set a standard to protect us with these invalid claim situations. Unfortunately this is not one of them but as you mentioned how would you know after reading the writing on the wall. I would always submit info to a company after a warranty period is up, maybe address it as "I understand the warranty is up but this seems a little off from what I would expect of this product blah blah blah....." For KC we look at everything and bring reality to the picture best we can as we truly value our customers, as i mentioned if it's our problem we are not afraid to admit it and handle it. I'll be on the look out!
