Example Input: I love how this product makes me look in my clothes!!! its shapes me into a perfect hourglass! i dont know if the claim that it permanantley reduces your waist after 30 days is true because i havent had it that long. my only complaints are that it is a little too short, so i still have a small bulge over the top in vthe back and i think it may be stretching out as i wear it as oppossed to it shrinking me, but overall, it is the best shapewear i have ever purchased. i love it and would recommend it to anyone.
Example Output: Positive

Example Input: These two short tapes consist of a brief description of 50 years of white-red relations, treaties and conflicts. Because of its brevity, there is little detail presented. The text is interesting and appears to be factually correct. The presentation is relatively unbiased, and is quite interesting. It would make a good audio tape. The extra loud background music and simulated battlefield noise sometimes drowns out the text. The visual portion consists of old photographs, presumably authentic in detail and clips from old grade B movies which are quite far from authentic. These are rerun from 6 to 10 times throughout the presentation and, of course, have no bearing on the text. Except for the extreme brevity and the overwhelming background noise, one can ignore the visual effects and derive a worthwhile understanding of many aspects of the period of the Indian Wars.
Example Output: Negative

Example Input: Purchased online, good description with size included. However, when it arrived it was larger than advertised (length and circumference). It was actually to large and caused some discomfort. It has a very hard plasltic like feeling which did not help with insertion. It seems to be well built if you are looking for the terminator of vibrators!! If you have had a few kids and need something bigger and harded, this is for you! For us it was a waste of the money spent as we will not be using it again.
Example Output:
Negative
