Task: Sentiment Analysis
Input (English): Perhaps I got a bad one? A factory second? For the first 3-4 days I wore mine, it was great, just as advertised, helped me fit into those pants that are just a tiny bit too snug around the waist. I was very happy and it helped me concentrate on my posture, too, although it was very difficult to turn in the car seat when backing out of a parking space! However, I put it on today, and while my left side is all smooth and nicely held in, the support thing (bone or whatever) under my right breast seems to have lost all its firmness. My entire right front is pushing outwards on that, making a vertical bulge; whereas my left side is still firm and compressed. I don't know what could be happening.
Output (English): Negative
