PROBLEM: 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: Positive

SOLUTION: False

PROBLEM: Review: Recently I ordered 'Stopped at Stalingrad' from amazon.com. It was well worth the puchase, as the book is both a profoundly researched study and an interesting read. It's a scholarly work which, undoubtedly, will become a classic in its field.Dénes Bernád, Aviation Historian and Author 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: I know that saying the book is dumb nullifies all the hard work put into it, but I just did not like it. Sure the main idea and a well written summary makes the book as a whole good, it doesn't help the actual context one bit which was very hard to follow and comprehend. 
 Polarity: Positive

SOLUTION:
False
