Query: DO NOT use to make smoothies

Contrary to product description, this unit is NOT good for making smoothies.We purchased this product last December. My wife has used it primarily for making salsa and general blending (nothing frozen).Last week we decided to try making our own smoothies. I made about a 32oz smoothie the first time and noticed the unit smelled like the motor was burned out. It continued to work the second day when I made almost a full jar; the smell came back and the unit was shaking. Now after 8 uses the motor will not turn.This product had such little use that should have lasted a lot longer. The Cuisinart replaced a Hamilton Beach dispensing blender that we paid about $40.00 for over two years ago and still worked when we gave it to my mother-in-law. She still uses it today.To make things worse, we can't find the receipt.
