Task: Sentiment Analysis
Input (English): Review: It all depends on your purpose for these safety pins. I needed them for holding Velcro in place as the Velcro was pulling apart too easily. These safety pins bent as I tried to stab them into the material. The point is sharp, but the surface is rough. This rough point causes the material to cling to the safety pin rather than allow the pin to pass through easily.I would recommend the Dritz Quilter's Safety Pins. They are Nickel plated which makes them smooth and rust resistant. 
 Polarity: Negative
Output (English): True
