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: Where to start I have had this for 10 years and it is still ticking that alone is a tesament to how well the thing works. Over that ten years It has traveled with me to over a third of the world. This is to include half a tour in Iraq. It has been dropped and has been trough airport security more times than most people. Because of this I have never had a reason to buy an Ipod. And to be honest for music I would rather use this. Only reason that I own anything like an Ipod is that its my Iphone. So I think that the Xtra is by far the one of the best mp3 player made.
Example Output: Positive

Example Input: The shape wear is difficult to put on and you can see the seams through your clothes. It is hard to bend over, especially as a school teacher! I would definitely like to try Brooke Burke's Belly Taut instead of this old school shapewear!

Negative
