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: Negative

SOLUTION: True

PROBLEM: Review: I was amazed to find out that this cable was so cheap and would work with my 1080p tv. Much to my surprise, the cable didn't respond too well to my tv and left me with black screens every so often. When I did my reasearch, I realized that not all HDMI cables are the same! If the cable is anywhere from $1 to $40, chances are it won't work well and isn't HDMI-Certified.Doesn't seem strange to only have to spend $1 on a High Definition cable when your tv and sound system probably cost around 3 grand?THERE ARE DIFFERENCES BETWEEN HDMI CABLES! NEVER BUY A CABLE UNLESS IT HAS BANDWITH, SPEED, COLOR, SOUND, AND FREQUENCY RATINGS ON IT! Also remember, the longer the cable the less data makes it out of the other side!Watch videos on Monstercable.com to learn more about which cable is best for you and you tv.

PROBLEM: Review: Horrible product! Too much talking about general stuff. Not enough real tests. Very low level of expertise. it is just ridiculous how people can get published with such book about nothing. Bits and pieces here and there. Please, Amazon, do not sell this book - too little of material for too much money. It's a SHAME!!!!!!!!!
