Example Input: I had problem with the 2 screen protectors, any of them paste well on the screen. Very disappointing because I also bought the complete screen protection and I hope not happening the same thing...
Example Output: negative

Example Input: Ordered size small in blue. I'm about 5'8, 150 lbs with more of an athletic build. This dress fits perfectly. The color is more vibrant than I thought it would be but I love it. Fabric is pretty good quality and there is a little stretch in it, but very comfortable. Very happy with this purchase.
Example Output: positive

Example Input: This shirt does NOT fit true to size at all. I ordered a LARGE which is what I typically wear, but this definitely does not fit like a large! I always fit in a large, but this shirt is tight on me.
Example Output:
negative
