Q: Title: A perfect Fit! Review: These are an exact match of all the parts needed to repair issues with my Craftsman 1/2 HP door opener.It comes with the shaft, main sprocket, gear on top, top plate, 2 other vinyl sprockets, a host of metals rings and some grease. Oh yes and some instructions :)Everything fit easily and quickly. Do listen to all the other reviewers and instructions when it says to first run the opener through a full opening cycle (without door attached) - - - before you go ahead and attach door trolley to chain! This ensures you attach trolley to chain at end of its opening cycle and not, somewhere in the middle where you door initially quit functioning...Bought the part for $25 and spent maybe 1 hour total removing and then installing new parts - q huge and worthwhile savings. I am not a mechanic nor particularly handy with tools - but Youtube has excellent videos explaining the process. Is the review positive or negative?

Q: Title: Good entertainment, mediocre sequel Review: The novel is certainly exciting and entertaining because it makes your heart pound with sheer adrenaline. The dangerous cat and mouse game that Pazzi and Lecter play--who is the mouse?--is one of the most fun parts of "Hannibal". We all realize early on that Pazzi will be one of Lecter's victims and suffer a ghastly death, but Pazzi's manner of death, when it does come, is beyond apalling. It is fierce, bloody, and well executed.The main disappointment was the revelation of Lecter's source of madness. I have always maintained that although Lecter is evil by nature, he seems to have a moral reason for killing. He ascribes to some higher understanding that his victims are too stupid to see. Only the select few can come into contact with him and not die. Disclosing his violent and cannabalistic nature as resulting from his sister's young death was a bit disappointing. I would have preferred Lecter's evil to be shrouded in mystery and incomprehensible. Is the review positive or negative?

Q: Title: Please read Review: So I purchased these glasses a bit ago. The first day I wore them, as I was walking to class, the screw holding the part that rests on your ear and the rest of the glasses falls and is lost forever. Then while i picked up the pieces the other screw fall out. I contact the seller and they told me they will send me a replacement. its been somewhere around two to three weeks and I have received nothing, not even an email. I would advise you to go to a store and by a pair that you could actually use and tell all your friends never to buy this product. It is terrible along with the seller. Is the review positive or negative?

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
