Input:
I have been using this product and think that it is a knock off.  I have purchased other kitchen aid items before and none have worked this poorly.  I tried to make a smoothy and the ice took a very long time to crush.  I gave the kitchen aid I have previously purchased for double the price to my mom and thought this purchase would be a steal, instead I got what I paid for.  This product should not have been endorsed with the kitchen aid logo.  If it is kitchen aid it was defected.

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