Query: Broke on the first use--do not buy!

The first time I used the blender out of the box it started burning up and small chips of plastic came out of the bottom. Since it was still under warranty, I sent it back (after paying for shipping myself) and they informed me (3 months after they received it for repair) that the needed parts were not covered: if I want it repaired I have to pay an additional 46 dollars AND pay for the return shipping! I will NEVER buy from cuisinart again--so disappointed.
