Title: Poor Written Instructions, Poorly Engineered Product Review: After reading the first two reviews, I plunged ahead with this purchase wondering "How hard can it be to install a retractable screen door?" Well, pretty much impossible with instructions written and illustrated by someone had apparently not tried to install the product themselves and definitely impossible with a heavy, clunky, ineffectively designed product. You can get it cheaper at Home Depot ($129.99) but, honestly, $1.29 is still too much to spend on this futile exercise. Save yourself the time and find another solution.

Title: excellent! Review: i loved this book. my brother stole it from his fifth grade teacher, and i borrowed it to read it. i didn't read any of the ones before it, but that's not important. the story was great! and the characters were wonderful. it is a small book, but the plot can get confusing at parts, but i figured it all out. i would recommend it to anyone to read again and again.

Q: Title: Terje can do more than atmospheric jazz! Review: This isn't a "typical" Rypdal CD, so I can see how some of his fans could be disappointed as the reviewer below. But it's still evocative music that deserves thorough listening. Not as lyrical-orchestral as his classic opus "Whenever I seem to be far away", this blending of the electric guitar with a "classical" ensemble is still impressive.

A: Positive

Question: Title: PENTEL CORRECTION PENS - the best! Review: Easily my favorite correction pen. I use it for pen & ink art work. The fluid is smooth and opaque, leaves minimal to no white flaky dust (no mess). Even the size of the pen itself is pliable and efficient. Highly recommended! This pen has become an integral member to the tools of my trade. Does this product review convey a negative or positive sentiment?
