Example Input: Beautiful wig arrived quick and well packaged. Lace fine. Lots of hair. Color lovely. Fit good hairline good. It's so pretty thats what gives it away as being a wig as no one's natural hair could be do uniformly pretty. Can part anywhere. Movie star hair.
Example Output: positive

Example Input: I am so excited to get this sweat vest! Fits great zips up easily. Fits and stays a lot better then a normal sweat band or waist trimmer. The smell of the material goes away as soon as you soak it in water with soap. But all and all great product.
Example Output: positive

Example Input: I like the design of the case and it has been pretty solid but I was pretty shocked to see that the part that holds the iPad up so you can type(which is the only reason you got this...) is simply glued to the hinges. Now that this part has come unglued from very very light use, there is literally no use for this case. For the price I'm super disappointed in how it turned out.
Example Output:
negative
