SJ wonders if Cuisinart might not want to destroy evidence at her expense

This is my Cuisinart Sucks story::  I am currently dealing with Cuisinart over a defective cookie sheet that almost burned down my house. I was using the easy grip baking sheet in my oven when smoke suddenly filled my kitchen and my smoke detector began to sound. I turned off the oven and pulled it out only to find that the food was uncooked, but the silicone grips were completely melted. I sent photos and a nice letter asking them to replace it. They want me to pay the shipping (which is almost the cost of the pan) so that they can "evaluate the situation." My thought is they want to destroy evidence at my expense.
