Input:
When I received my Waring blender, I opened the box and assembled the appliance.  I decided to wash the blender jar prior to using it for food and take it for a test spin.  I filled the container one-third full of water and added a drop of liquid detergent.  I plugged the unit in and flipped on the  switch-- PRESTO-- there was a loud hum, the motor was smoking, and the blade sat frozen in the blender. I try to find the humor in this, but cannot. I'm returning this defective piece of garbage for a full refund.  Frankly, I've never purchased an appliance that wasn't carefully tested in the factory before being shipped out to the consumer.  I wish I had read the reviews on this flimsy product before wasting my time with purchasing it.

Options:
A: very positive
B: positive
C: neutral
D: negative
E: very negative
Answer: E: very negative
