Input: Consider Input: The lady is kinda annoying. But the videos made me feel prepared and made me feel comfortable with my decision to not go to any formal classes, these were more than enough.

Output: Positive

Input: Consider Input: I got this item within a few days of my purchase. It is exactly what I wanted -- I look a whole size smaller, instantly. I tried on the Squeem in a boutique and fell in love, but they were asking almost $200 for it! I highly recommend this item and the seller.

Output: Positive

Input: Consider Input: We purchased six of these heaters in February 2006, and by November 2006 only one was still working. One was DOA, two died within one week of arrival, and the other two died over the next seven months. We live in Southern California so these heaters were rarely used so its not like they wore out. Repeated calls to DeLonghi customer service went unanswered, and the local service company they refer to in their service manual is no longer in business. We are very disappointed with the heaters and DeLonghi and would not buy one from them again.
Output: Negative
